Access Issue: New Emergency Closure Details

Emergency Raptor Closure of Der Freischutz and surrounding formations:

OSMP is enacting a closure to protect cliff nesting raptors at Der Freischutz on Dinosaur Mountain — please see the attached map. The closure includes the BUBBLE and the Dinosaur Eggs formations.

On Wednesday of this week, OSMP staff and volunteers observed that the prairie falcon pair that typically occupies Bear Creek Spire had relocated to the Der Freischutz formation.

The pair’s timing is in the ballpark that if they succeed and fledge young, the formation will open with other closures on or about July 31st.

As a result of the move, OSMP is lifting the closure for Bear Creek Spire.

Those approaching Overhang Rock from Mallory Cave trail will need to approach from Bear Creek Spire going forward or until Bear Canyon trail is reopened.

Description

The Bubble is a large boulder located in a gully north of Bear Creek. It is home to Hot Spit and Cold Sweat, both of which are on the east side. The crag offers great climbing on short and powerful routes in an isolated area of Dinosaur Mountain.

Getting There

Two hiking routes can lead you to the Bubble, both of which are approximately the same distance. The first hike begins at the Bear Canyon trailhead and ascends to the Mesa Trail. Take the Mesa Trail east (about _ mile heading upwards) to the Bear Canyon turnoff and then head west (another _ mile) to the rock Stonehenge, home of Thought Control, the Fiend, and others. From Stonehenge, go north up a gully for about 100 meters and it will be on the east side, just past Sneak Preview. The second hike begins at NCAR and ascends the Mallory Cave trail up to the climbers' trail (near Der Zerkle) to the Drugs/Power Bulge area. From this alcove, descend the gully heading south and the Bubble is about half way down (~100 yards) to the base of the canyon.(See also directions to Stonehenge and other Dinosaur Mtn. crags).
