澳门开奖结果2023开奖记录 graduate delves into the deepest parts of Colorado mountains in search of the strange

As a freshman living in Stearns West Hall, Dave Steinmann (Phys, Bio鈥�90)鈥檚 roommate, Dave Mckee, mentioned something that would prove life-changing: His father had an unusual hobby of exploring dark places where there are strangely beautiful, ancient life forms.听

That was 1984. Today, Steinmann, 54, is a cave dweller too, but with federal permits to collect specimens and a team of experts who have confirmed his discoveries of more than 100 new species that thrive within the craggy walls and tubelike passages of Colorado鈥檚 high-altitude caves.

鈥淚n every cave, I guarantee there is something new to discover,鈥� says Steinmann, whose work has been featured in National Geographic Magazine. Minuscule millipedes, spiders and pseudoscorpions鈥攈alf-inch long relatives without a stinging tail鈥攁re among his collections.

Steinmann is a special breed, explains Frank-Thorsten Krell, senior curator of entomology for the Denver Museum of Nature & Science, where Steinmann is a research associate. 鈥淓xploring places that are hardly accessible and outright dangerous requires a certain mindset and a lot of expertise. Both he has. He is amazing.听So much talent, expertise, and eyesight! I think he is the only or at least the by far most prolific discoverer of new cave life in Colorado and probably the Rocky Mountain Region.鈥�

On a personal level, it鈥檚 fascinating to think about life that evolved over millions of years in the coldest, harshest climates, Steinmann says. 鈥淚t鈥檚 amazing to look at body formations under the microscope and see creatures that are albino because of no sunlight, covered in sensory hairs used for feeling their way around, and most often have no eyes.鈥�

Explorer at heart

Born in Illinois, the Steinmann family lived in Boulder for his dad鈥檚 postdoctoral studies in psychology at the 澳门开奖结果2023开奖记录 but moved when Steinmann was 7 years old.

鈥淚 remember thinking how nice Boulder was, and immediately planned to go to college here,鈥� he says.

At 澳门开奖结果2023开奖记录, the unparalleled quality and charm of his science professors鈥攎any he routinely sees when dropping off specimens at 澳门开奖结果2023开奖记录鈥檚 Museum Herbarium鈥攚as most memorable, he says, notably the late Professor Emeritus William (Bill) Weber, who helped Steinmann become a rare-plants specialist.听

When he鈥檚 not exploring caves, Steinmann is working at his other job as a wetland鈥檚 consultant, including projects for the city of Boulder. Both endeavors, he says, resonate with a purpose to increase our knowledge of biodiversity in unusual places.听

鈥淢ost people think of wetlands as a lake with cattail swaths, but I鈥檓 usually the one who will be on the side of the hill looking at microhabitats for rare plants and insects.鈥�

Steinmann has always been an inquisitive soul, his longtime friend, Ross Dinkelspiel, says. 鈥淗e got me into caving and changed my perspective on life underground,鈥� he says. 鈥淏ut I could never see any of those darned tiny bugs that Dave could find.鈥�

Steinman even recently found a new species of daddy longlegs in Mallory Cave near the Flatirons. Genetic studies have shown these harvestmen evolved from their surface ancestors nearly 10 million years ago.

And as a volunteer firefighter who lives in Gold Hill, Steinmann spends a good amount of time cutting trees, clearing grass and shrubs surrounding his home. During the 2010 Fourmile Canyon Fire, neighbors credited Steinmann for saving their community by spraying a foam barrier that slowed and evaporated 100-foot-tall roaring flames, according to Colorado Public Radio. He was on standby during this year鈥檚 unprecedented fires that came close to town. 鈥淥ur house is fine, and we have a dog, Mishka, plus a cat and two toads that we evacuated.鈥�

But if you ask him, his heart belongs to cave research.

鈥淐aves are sensitive and irreplaceable ecosystems,鈥� he says. 鈥淢y goal is for others, especially young students, to discover caving.鈥�

Life underground

Colorado has no shortage of caves to explore, Steinmann says. The longest鈥擥roaning Cave north of Glenwood Springs鈥攐ffers 12 miles of passageways leading into rooms with 100-foot-tall ceilings, adorned with giant stalactites or icicle-shaped mineral formations hanging from the ceiling, and stalagmites jutting from the earth floor like the open jaw of a mythical creature.

To reach these chambers, it takes a lot of bending, twisting and squeezing his 6-foot-5 body through tight passageways, in the dark while shining lights on (hopefully) anything moving. Humidity can reach 100 percent, while temperatures are near freezing, sometimes there鈥檚 waist-high water and debris to navigate, with house-sized boulders that could drop in an instant.

鈥淪ometimes I feel like I鈥檓 on an Indiana Jones movie set,鈥� Steinmann says, 鈥渂ut it鈥檚 a little gross,鈥� because the tiniest critters are found on bat and pack rat droppings. So tiny, that it takes a wet paintbrush to collect rare invertebrates without damage.

During one outing, covered by National Geographic, he spotted masses of wriggling blood-red worms at Sulphur Cave in Steamboat Springs. The importance of this discovery鈥攁nd what it took to collect them鈥攕houldn鈥檛 be understated, says Krell of Denver鈥檚 museum, which preserves the specimens.

鈥淚t鈥檚 a deadly place for humans,鈥� Krell explains, as the worms live in sulfuric acid, which drips from otherworldly hanging white blobs called snottites that 鈥渨ould dissolve your clothes.鈥�

These tiny worms, Krell says, 鈥渕ight become interesting for medical research, astrobiology or the understanding of potential life on other planets.鈥�

Most discoveries are named after Steinmann, and one pseudoscorpion (Onychiurus nathanieli) was named after his son, Nathan, who recently applied to 澳门开奖结果2023开奖记录 and has been exploring caves with dad (and mom, Debbie) since he was 4 years old.听

Next up is a trip to a Western Slope cave that鈥檚 home to primitive lampshade spiders, named for their hanging web shapes and dating back to a time when the Earth held one continent. 鈥淭hey are big and run very fast,鈥� he says. 鈥淛ust seeing new species can be wonderful,鈥� Steinmann says. 鈥淒oes it necessarily benefit people? Maybe. But to show life exists in unusual places where you don鈥檛 expect to find it, I feel that鈥檚 enough.鈥�
