October 28, 2025

Editor’s note: Last week I had the pleasure of speaking at the San Juan Citizens’ Alliance celebration of 50 years of the Weminuche Wilderness, Colorado’s largest wilderness area at nearly 500,000 acres. Congress passed the legislation establishing the Weminuche in 1975, and it now covers some of the most spectacular landscape in the nation. This is an adapted version of the talk I gave (with a lot fewer umms and uhhs in it).

As I’m sure you all are aware, our public lands have been under attack for a while now, but especially in the last nine months, from both the Trump administration and from the Republican-dominated Congress.

This all out assault has given me many reasons to worry about the fate of some of my favorite places. I have worried about Sen. Mike Lee, the MAGA adherent from Utah, selling off Animas Mountain or Jumbo Mountain to the housing developers; I have fretted about Trump shrinking or eliminating Bears Ears, Grand Staircase-Escalante, or Ancestral Footprints of the Grand Canyon national monuments and opening them to the latest uranium mining rush; and I worry that regulatory rollbacks and the administration’s “energy dominance” agenda will make the San Juan Basin and the Greater Chaco Region more vulnerable to a potential new natural gas boom driven by data center demand for more and more power.

But one place I haven’t worried (as much) about being attacked by the GOP and Trump is the Weminuche Wilderness. That’s not because I think Trump or Lee are above messing with wilderness areas. They aren’t. In fact, just this week they opened the Arctic National Wildlife Refuge up to oil and gas leasing. Still, the Wilderness Act is one of the few major environmental laws these guys haven’t gone after directly — at least so far.

But more than that, the reason I feel the Weminuche is less vulnerable to MAGA attacks is because I am confident that even the most die-hard anti-environmentalist sorts understand that an attack on the Weminuche would be an attack on this region and its identity. The Weminuche has simply become ingrained in the collective psyche of southwest Colorado and beyond. If the feds were to try to open it to logging or drilling or mining or any other sort of development, there would be a widespread, deep revolt from this entire region, even from many a Trump voter.

In part, that’s because of how special the place is, with or without a wilderness designation. But it also has to do with the way the wilderness was established, and the widespread local support it ultimately garnered.

Not long after the Wilderness Act of 1964 was signed into law, federal and state agencies and residents of southwestern Colorado began talking about establishing a wilderness area in the remote San Juan Mountains. Areas such as the Silverton Caldera had been heavily mined, and no longer qualified for wilderness designation (even if the mining industry and local communities would have allowed it).

But the heart of the San Juans in and around the Needle and Grenadier ranges certainly fit the bill. In 1859, Macomb expedition geologist J.S. Newberry described the San Juans as a “thousand interlocking spurs and narrow valleys, [which] form a labyrinth whose extent and intricacy will at present defy all attempts at detailed topographical analysis. Among these are precipices, ornamented with imitations of columns, arches, and pilasters, which form some of the grandest specimens of nature’s Gothic architecture I have ever beheld. When viewed from some nearer point they must be even awful in their sublimity.”

“Awful” might be a bit harsh, but sublime? Indeed. That this should become a wilderness must have seemed like a no-brainer.

Nevertheless, the process to designate the Weminuche was no slam dunk. It took a half decade of wrangling and debate and boundary adjustments and congressional committee sausage-making. What to me is most remarkable, however, looking back on the process from our current, politically polarized era, is that the debates were not partisan. And even though there were differing opinions on where the boundaries should be drawn or even whether there should be any wilderness at all, the conversation was just that: a conversation, and a civil one at that.

Proposals were forwarded by the Forest Service and the Colorado Game & Fish Department. Meanwhile, the Citizens for the Weminuche Wilderness — made up of local advocates, ranchers, scientists, business people, and academics — came up with its own proposed boundaries.

My father chronicled some of the back and forth in an insert he put together and edited for the Durango Herald in 1969 called “The Wilderness Question.” It includes his editorials and news stories, but also opinion pieces from a variety of residents.

Looking back, it is a truly striking document. First off, there’s the fact that the Forest Service’s original proposal would have excluded Chicago Basin — now considered the heart of the wilderness area and a Mecca for backpackers and peak-baggers (and their attendant impacts) — and the City Reservoir trail and surrounding areas. They were left out, in part, because there were hundreds of mining claims in those areas, and the mining industry remained interested in them, despite their remoteness and difficult access.

The citizens group, however, was having none of that, and demanded that both areas be included in the wilderness area. Carving these areas out would be like cutting the soul from the place. Ranchers weighed in, as well. James Cole, who was described as a “prominent Basin rancher,” wrote this for the Herald supplement: “The La Plata County Cattlemen are in favor of the proposed Weminuche Wilderness Area … We would like to see Weminuche Creek and Chicago Basin, which the forest service would like to exclude, included in the Wilderness Area.”

It may seem odd, today, to see a livestock operators’ group advocating for morewilderness than even the feds wanted, but it makes a lot of sense. Not only are many ranchers conservation-minded, but their operations were unlikely to be affected by wilderness designation, since grazing is allowed in wilderness areas. It’s actually far stranger to see southeastern Utah ranchers become some of the most zealous opponents of Bears Ears National Monument, since its establishment didn’t ban or restrict current grazing allotments.

Fred Kroeger, a lifelong Republican1 and local water buffalo, who for years pushed for the construction of the Animas-La Plata water project, supported wilderness designation because it would protect the region’s water. (My grandparents, who were Animas Valley farmers and Republicans also supported the designation).

John Zink was a rancher, businessman, fisherman, and hunter and member of the citizens’ committee. In the Herald supplement he wrote that the proposed Weminuche Wilderness, “offers outdoor lovers an opportunity to support another sound conservation practice.”

He continued:

“For me it won’t be many years until slowed feet and dimmed eyes make the south 40 the logical place to hunt, and when the time comes, I expect to enjoy it. But a new and younger generation of outdoor lovers will then be climbing the peaks and wading the icy streams. I ask all outdoor enthusiasts to support the proposed Weminuche Wilderness Area, so each new generation may enjoy it much as it was when Chief Weminuche led his braves across this fabled land.”

That’s not to say everyone was in favor of the citizens’ proposal, but opposition was almost always on pragmatic, not political or ideological grounds. Probably the most strident opposing opinion piece in the Herald supplement came from an engineer at the Dixilyn Mine outside of Silverton, who didn’t want his industry shut out of any potentially mineralized areas, including Chicago Basin. Less than two decades later, the mining industry would be all but gone from the San Juans — and it had nothing to do with wilderness areas or other environmental protections.

John Zink’s son, Ed, who would go on to become a prominent businessman, pillar of the community, and the driving force establishing Durango as a cycling hub, asked that some areas, including the trail to City Reservoir, be excluded from the wilderness to accommodate the rights of “riders of machines.” He was talking about motorbikes back then, but would later focus more on mountain bikes. Zink, a staunch Republican, was undoubtedly bummed when the City Reservoir trail was included in the wilderness area, per the citizens’ proposal.

Nevertheless, a few years later, when I was about eight years old, I went on one of my earliest backpacking trips up the trail with Zink (who was my dad’s cousin), along with his sons Tim and Brian, nephew Johnny, and my dad and my brother. We hiked for hours without seeing anyone else — and without hearing the buzz of any motorized vehicles. Ed didn’t seem to miss his motorcycle one bit, nor did he or other motorized groups file lawsuits to try to block or shrink the wilderness, as is common practice today.

Ed would later be instrumental in establishing the Hermosa Creek wilderness area north of Durango, a compromise bill that left Hermosa Creek trail open to mountain bikes and motorbikes. Again, he worked from a pragmatic mindset: He wanted to protect the watershed from which his irrigation and drinking water came, and the forests that sustained game and wildlife, while also retaining recreational access.

When Congress finally passed the bill establishing the Weminuche, it went with the citizens’ group proposal and then some, designating 405,000 acres of federal land as a wilderness area and including Chicago Basin and City Reservoir. The Weminuche Wilderness was expanded in 1980 and again in 1993.

In the years since, public lands protection and conservation have become more and more politicized, along with just about everything else. The pragmatism of the 1970s has been abandoned in favor of ideology; public lands, somehow, have become a pawn in the culture wars. I’m sure both parties share some of the blame, but judging from their actions of late, the MAGA Republicans have become the staunchly anti-public lands conservation party — and bear absolutely no resemblance to the old school Republicans who fought for wilderness designation 50 years ago. Hell, for that matter, some Republican politicians don’t even resemble their selves from just a couple of decades ago.


The death of the pragmatic Western Republican: Extremism is killing the old-school GOP — Jonathan P. Thompson


Trump’s going to go away some day, and the attacks on public lands will probably ease off. But they won’t stop altogether. Humans’ hunger for more stuff and minerals and energy will undoubtedly put pressure on the places we hold dear, maybe even on the Weminuche. But polarization and political partisanship will only hamper our ability to save these places. Our only hope is to, somehow, recover some of the civility, the non-partisanship, and the pragmatism that fueled the designation of the Weminuche in 1975.

I have no idea how we’ll get there, but I do hold out hope. I really have no choice. I’ll leave you with some words written by my father, Ian Thompson, in the “Wilderness Question” insert in 1969:

“The Wilderness effort we are engaged in at the time is, in one respect, a pitifully futile struggle. Earth’s total atmosphere is human-changed beyond redemption, Earth’s waters would not be recognizable to the Pilgrims. Earth’s creatures will never again know what it is to be truly “wild.” The sonic thunder of man’s aircraft will increasingly descend in destructive shock waves upon any “wilderness area” no matter how remote or how large. No, there is no wilderness, and throughout the future of humanity, there will be no wilderness. We are attempting to save the battered remnants of the original work of a Creator. To engage in this effort is the last hope of religious people.

“The child seen here and there in “The Wilderness Question” would have loved Wilderness. There is tragedy in that knowledge. Hopefully we will leave him a reasonable facsimile of Wilderness. In the last, tattered works of Creation this child might find the source of strength necessary to love America and the works of man. If we care enough to act.”

*Nowhere in the several-page insert are political parties mentioned, most likely because people were less inclined to identify themselves according to political party, but also because environmental preservation was not at all partisan at the time. I mention their affiliations here to further demonstrate the way the discussion transcended party politics.


Speaking of the Weminuche: It looks like wolves may have made their way into the wilderness area. Colorado Parks and Wildlife’s most recent Collared Gray Wolf Activity map shows that the wolves have been detected in the San Juan, Rio Grande, Uncompahgre, and Gunnison River watersheds in the southwestern part of the state. Since the minimum mapping unit is the watershed, it’s not clear that the wolves have for sure ventured into the Weminuche. But it is certain that they have been recorded in the San Juan Mountains. It seems only a matter of time before they cross into New Mexico and maybe even Utah.


When Trump was elected for the second time, I figured there was no way he could make public lands grazing any less restrictive. After all, presidential administrations of all political persuasions have famously — or infamously — done very little to restrict grazing or to get it to pay for itself (the BLM’s grazing fee has remained at $1.35 per AUM, the mandated minimum) for decades. But, alas, the U.S. Agriculture Department recently announced its plan to “Fortify the American Beef Industry: Strengthening Ranches, Rebuilding Capacity, and Lowering Costs for Consumers.” 

The plan, as you may imagine, looks to expand public lands grazing, among other things. And it was released at about the same time as Trump encouraged folks to eat Argentinian beef, since he seems to have developed a sort of crush on Argentina President Javier Milei. 

I’ll get into the details of the USDA plan and offer some thoughts on it in the next dispatch. In the meantime, you can dive into my deep dive on public lands grazing here, though you have to be a paid subscriber (or sign up for a free trial) to get past the paywall.

A new University of California San Diego study uncovers a hidden driver of global crop vulnerability: the origin of rainfall itself.

Published in Nature Sustainability, the research traces atmospheric moisture back to its source—whether it evaporated from the ocean or from land surfaces such as soil, lakes and forests. When the sun heats these surfaces, water turns into vapor, rises into the atmosphere, and later falls again as rain.

Ocean-sourced moisture travels long distances on global winds, often through large-scale weather systems such as atmospheric rivers, monsoons, and tropical storms. In contrast, land-sourced moisture—often called recycled rainfall—comes from water that evaporates nearby soils and vegetation, feeding local storms. The study finds that this balance between oceanic and terrestrial (land) sources strongly influences a region’s drought risk and crop productivity.

“Our work reframes drought risk—it’s not just about how much it rains, but where that rain comes from,” said Yan Jiang, the study’s lead author and postdoctoral scholar at UC San Diego with a joint appointment at the School of Global Policy and Strategy and Scripps Institution of Oceanography. “Understanding the origin of rainfall and whether it comes from oceanic or land sources, gives policymakers and farmers a new tool to predict and mitigate drought stress before it happens.”

A New Way to Forecast Drought Risk

Using nearly two decades of satellite data, Jiang and co-author Jennifer Burney of Stanford University measured how much of the world’s rainfall comes from land-based evaporation. They discovered that when more than about one-third of rainfall originates from land, croplands are significantly more vulnerable to drought, soil moisture loss and yield declines – likely because ocean-sourced systems tend to deliver heavier rainfall, while land-sourced systems tend to deliver less reliable showers, increasing the chance of water deficits during critical crop growth stages.

This insight provides a new way for farmers and policymakers to identify which regions are most at risk — and to plan accordingly.

“For farmers in areas that rely heavily on land-originating moisture — like parts of the Midwest or eastern Africa — local water availability becomes the deciding factor for crop success,” Jiang explained. “Changes in soil moisture or deforestation can have immediate, cascading impacts on yields.”

Two Global Hotspots: The U.S. Midwest and East Africa

The study highlights two striking hotspots of vulnerability: the U.S. Midwest and tropical East Africa.

In the Midwest, Jiang notes, droughts have become more frequent and intense in recent years — even in one of the world’s most productive and technologically advanced farming regions.

“Our findings suggest that the Midwest’s high reliance on land-sourced moisture, from surrounding soil and vegetation, could amplify droughts through what we call ‘rainfall feedback loops,’” Jiang said. “When the land dries out, it reduces evaporation, which in turn reduces future rainfall—creating a self-reinforcing drought cycle.”

Because this region is also a major supplier to global grain markets, disruptions there have ripple effects far beyond U.S. borders. Jiang suggests that Midwestern producers may need to pay closer attention to soil moisture management, irrigation efficiency and timing of planting to avoid compounding drought stress.

In contrast, East Africa faces a more precarious but still reversible situation. Rapid cropland expansion and loss of surrounding rainforests threaten to undermine the very moisture sources that sustain rainfall in the region.

“This creates a dangerous conflict,” Jiang said. “Farmers are clearing forests to grow more crops, but those forests help generate the rainfall that the crops depend on. If that moisture source disappears, local food security will be at greater risk.”

However, Jiang sees opportunity as well as risk:

“Eastern Africa is on the front line of change, but there is still time to act. Smarter land management — like conserving forests and restoring vegetation — can protect rainfall and sustain agricultural growth.”

Forests as Rainmakers

The research underscores that forests and natural ecosystems are crucial allies in farming. Forests release vast amounts of water vapor into the atmosphere through evaporation and transpiration (when plants produce moisture), effectively seeding the clouds that bring rain to nearby croplands.

“Upland forests are like natural rainmakers,” Jiang said. “Protecting these ecosystems isn’t just about biodiversity—it’s about sustaining agriculture.”

A Tool for Smarter Land and Water Management

Jiang’s research provides a new scientific framework connecting land management, rainfall patterns and crop planning — a relationship that could become central to future drought resilience strategies.

The study’s novel satellite-based mapping technique could help governments and farmers identify where to invest in irrigation infrastructure, soil water storage and forest conservation to maintain reliable rainfall.

#California’s 2025 use of #ColoradoRiver water is on track to be the lowest since 1949 — John Fleck (InkStain.net)

Lower Basin water use since 1964. 2025 data provisional, based on USBR projections Oct. 29, 2015.

October 31, 2025

California’s projected use of Colorado River water this year, 3.76 million acre feet as of Reclamation’s Oct. 29 modeling runs, would be, as near as I can tell, the state’s lowest use since 1949.

Also notable:

  • Nevada’s 197,280 acre feet would be the lowest since 1992.
  • The two lowest years in Imperial Irrigation District’s history (my dataset goes back to 1941) were last year and this year.
  • This will be the third year in a row that Arizona’s main stem use has been below 2 million acre feet. The last time that happened (three consecutive years below 2maf) was in the 1980s.

Total take by the US Lower Basin states is projected to be 5.917 million acre feet, the lowest total US main stem use since 1983.

A few things to note.

First, the tenuous fabric of the Basin States negotiations is predicated right now, in part, on the Lower Basin cutting 1.5 million acre feet of annual use. They’ve already done that.

Second, the current cuts are enabled by significant federal payments to compensate the water agencies for their cuts. As my colleagues and I wrote back in September, counting on that money in the future would be unwise.

Third, the economies of Arizona, southern Nevada, and southern California are chugging along just fine right now. As I have written in the past, having less water does not mean scary doom. We can do this.

A note on the data:

The projection of total 2025 use by Lower Basin water users is based on model runs done by the Bureau of Reclamation every few days. It’s a rich source of data, with detailed accounting of the various conservation programs being run by the Lower Basin agencies. PDF here.

The comparison with prior years is based in part on the Lower Basin accounting reports, prepared each year since 1964. For prior years, I have a dataset I got years ago from the technical staff at the Metropolitan Water District of California, who had pieced together California numbers back to 1941. (Thanks, Met!)
