Geology & Natural History

“Why not eat insects?” Jim Wangberg asked this in 1987, and it set off more than a classroom discussion. At the time, Wangberg was department head of plant, soil and insect sciences at the University of Wyoming. His question was particularly pressing following Wyoming’s big grasshopper years in 1985 and 1986, with densities of up to 100 grasshoppers per square yard in some locations. That many grasshoppers can devastate an agricultural based economy.

Whoopup Canyon, a system of roughly 150 rock art panels along a four-mile stretch of Dakota sandstone in northeast Wyoming, is a special place. Its petroglyphs, mostly images of game animals, are among the most extensive and among the oldest in North America.

One fine summer morning in 1871, the sailboat Annie launched from the north shore of Yellowstone Lake—the first known boat to traverse its waters. Read more about this exciting chapter of the epic Hayden Geological Survey in Jett B. Conner’s article, The Annie.

Since the late 1940s, birders in Casper and around the state have pursued annual Christmas bird counts, providing reams of data for a fast-changing world. Rising early and working late, birders live to listen, watch and learn—and the birds keep flying.

No landscape is beyond the reach of history. The wilderness of the Absaroka Mountains, bordering the west side of Wyoming’s Bighorn Basin, is no different. Evidence of early mining activity still endures in isolated pockets, and searchers can still find cabin ruins, tailings and a few crumbing tunnels.

Historian, botanist, teacher and rancher Vie Willits Garber grew up in Big Horn and in 1910 earned a master’s degree in two disciplines from the University of Wyoming. She was the first person to carefully map and document the route of the Bozeman Trail—and she identified and listed 615 plants in the Little Goose Valley near her family’s home.

After Yellowstone rangers slaughtered 4,300 elk in 1961 to try and control overpopulation, hunters, outfitters and the public were enraged. In response, zoologist Starker Leopold, son of famed naturalist Aldo Leopold, wrote a groundbreaking report for the National Park Service that advocated systematic, scientific management of natural areas—a revolutionary approach at the time.

A Nobel Prize, big business and scientific breakthroughs including Covid-19 tests and vaccines were decades in the future when microbiologist Thomas D. Brock began taking samples from Yellowstone Park’s hot springs in the summer of 1964.

When present Wyoming was still part of Dakota Territory, hunters already were killing elk, deer and antelope by the thousands, often to sell the meat and hides. Tentatively at first and then more strongly, Wyoming territorial and state legislatures began passing game laws—and providing for their enforcement.

Guided by a pair of Kentuckians, four blindfolded investors rode south from Rawlins toward the Colorado border in June 1872. Their objective, they thought, was a vast, secret field of diamonds, but they lost nearly all the money they’d put in and the swindlers got away—for a time.
