Set within the rugged contours of South Fork of St. Vrain Canyon, Oxygen Masks and Float Cushions offers climbers a raw and less-trodden trad route that tests technique and patience in equal measure. The climb unfolds over a single 100-foot pitch where you will find an engaging mix of solid rock and unexpected moves that demand both focus and finesse. Starting just a few meters left of Flight Attendant, the approach takes you beneath an overhanging roof before entering a quiet crack system, still adorned with patches of lichen that speak to its remote frequency. This route may not boast the lithe, polished holds of its neighbor Aviatrix, but its gritty, understated character delivers a rewarding experience for climbers seeking an offbeat line.

The climb’s character is shaped by its wandering path: an initial ascent upward and left below the roof transitions into a rightward finger traverse past a tangled bush clinging stubbornly to the rock. Passing this natural obstacle isn't a struggle if you opt to skirt right—here, patience pays off more than brute force. The following crack system, perched a few meters right of the bush, invites you into steeper terrain, culminating in a small bulge that demands solid jamming and confident gear placements. Protection is straightforward yet crucial; a standard rack to 3" gear suffices while an optional 4" piece can be placed for added security if desired. Longer slings come in handy when negotiating the pitch’s subtle shifting lines.

Despite its somewhat mellow rating of 5.8 PG13, the pitch presents moments of awkward body positioning and moves that can catch you off-guard, so approach it with deliberate attention. The pathway feels raw and unpolished—rock whispers its primal solidity underfoot, and the occasional lichen patches remind you this route is still growing into itself. Reaching the large belay tree at the top offers relief and a moment to savor the quiet canyon views spreading below.

Approaching the Stewardess Convention Crag requires a short trek that rewards with a peaceful and relatively untouched climbing experience. The crag itself is known for its variety of trad routes, ranging from straightforward to technical, set against the vibrant backdrop of Lyons, Colorado. Temper your expectations for crowds here; oxygen masks and float cushions attract climbers who appreciate a bit of solitude and the challenge of routes that aren’t standing-room-only. With proper preparation—sturdy footwear for the approach, layers for the variable canyon climate, and extra hydration—you can focus on the climb’s subtle complexities.

The route’s projection across shaded sections of the wall makes mid-morning to early afternoon climbs ideal, especially during spring and fall when the temperatures balance out Colorado’s sharp summer heat and winter chill. Descending involves a well-established walk down from the belay tree, though loose footing demands caution during the exit.

In essence, Oxygen Masks and Float Cushions is an understated gem for trad climbers eager to explore the creative puzzle of crack systems and traverse lines within a quiet, bold environment. It promises a blend of adventure and practicality—a relying on solid gear, patient climbing, and an appreciation for the rough edges that craft the route's unique identity in the St. Vrain canyons.
