Carpenter Ranch (The Nature Conservancy)
The Nature Conservancy bought this 906-acre spread in 1996 and kept the cattle — hay crews still cut the fields where western Colorado’s densest Bobolink colony nests. The house belonged to Ferry Carpenter: Princeton, Harvard Law, Hayden’s first lawyer, and the New Deal maverick who ran 258 million acres of public rangeland with under thirty employees until Interior Secretary Ickes fired him. He took the place over in 1926 from J.B. Dawson, an ex-Texas Ranger. Summer mornings, you just walk in.

Sulphur Cave at Howelsen Hill
The town ski hill has a cave that can kill you in two breaths. Sulphur Cave drops about fifteen feet into travertine just west of the lower Mile Run, exhaling hydrogen sulfide so thick researchers enter only in supplied-air gear. Inside: dripping snottites of sulfur-eating slime and wriggling blobs of blood-red worms, Limnodrilus sulphurensis, that live nowhere else on Earth. The feds made it a National Natural Landmark in 2021. You stand at the fence, catch the rotten-egg breath, and peer in.

Sunpie's Bistro
Two New Orleans transplants opened this Yampa Street dive in 2005, named it for zydeco great Sunpie Barnes, and covered every inch of wall and ceiling in Mardi Gras bric-a-brac before selling it in 2012 to locals smart enough to change nothing. The move: a 20-ounce rum Hurricane and a fried shrimp po'boy carried out back, where the beer garden grass runs straight to the Yampa River. The hook-and-ring toss game eats hours, and the gumbo only shows up after Labor Day.

Deadman Fire Lookout Tower
Built by Civilian Conservation Corps crews in 1937–38 and replaced with the current 55-foot steel tower in 1961, Deadman Lookout stands at 10,710 feet in Roosevelt National Forest above the Laramie River Valley. On clear days the observation cab — still fitted with an original Osborn firefinder, a circular sighting device manufactured before 1975 — delivers panoramic views stretching 110 miles into Wyoming. Volunteer hosts staff the tower on a summer schedule, walking visitors through the history of fire detection and the women like Bernice George who spotted blazes here during the 1940s. The original CCC wooden-tower footings are still visible on a short walk east of the current structure.

Owl Canyon Gliderport
About 15 miles north of Fort Collins on 256 acres of high-plains prairie, the Colorado Soaring Association's Owl Canyon Gliderport (FAA: 4CO2) has operated since the 1960s. Scenic rides put you in the front seat of a two-place sailplane while an FAA-certified commercial pilot flies from behind. A towplane hauls you to altitude over the flatlands stretching east toward Nebraska; the pilot releases the tow rope, the engine noise disappears, and you're in silent thermal flight with a panoramic view of the Front Range. Duration flights of over five hours and altitudes above 17,000 feet are routine for members in summer thermal conditions.

Gnome Road (Elf Lane)
Somewhere between Lake Hiawatha and Lake Apache, a hand-lettered sign warns you not to take, break, or relocate the residents — which is your first hint that this quarter-mile dirt lane is doing something. Ceramic elves peer out of tree roots, trolls wearing mushroom caps cling to bark, fairy doors are mortared into trunk hollows, and a plastic SpongeBob holds his position in the scrub like he's been there forever. Nobody organized this. Decades of anonymous mountain-town contributions just kept accumulating, and the lane absorbed all of it without comment.

Crown Point B-17 Crash Site
On June 13, 1944, a fully crewed Army Air Forces B-17 slammed into a snow-covered mountainside north of Crown Point and killed four of its ten men — pilot Drury Holt among them — in a place locals still call Hell's Half Acre. Nearly 80 years later the wreckage is still there: shredded fuselage panels, mangled engine components, and bomber fragments scattered across a boulder field at around 11,000 feet. Green metal tags nailed to trees are the only navigation aid on the final approach, which the trail guides charitably describe as a treasure hunt. Six men walked away from this; standing in the debris field, that fact is somehow the most unsettling part.

Virginia Dale Overland Trail Stage Station
Jack Slade built this home station in 1862, then allegedly robbed a stage of $60,000 in gold that was never recovered — the station still stands on its original footprint, the last of its kind on the entire Overland Trail. It's private property now, owned by the Virginia Dale Community Club, which means the building is quietly occupied rather than roped off and museumified. Drive 45 miles up US-287 toward Wyoming and you'll pass it on the east side of the highway looking exactly like a 164-year-old ranch outbuilding, because it is. Mark Twain met Slade's boss at a nearby station and wrote about it in Roughing It — this is the one that came after the famous meeting.
