Seasonal Closures March 1-July 31. Per this RMNP website, "Initial closures occur in March and April, when raptors return to the region and scout for nesting sites. Areas containing general habitat preferred by raptors are closed during this time. Once raptors have selected nesting spots, the initial closures are lifted or adjusted. The specific areas which raptors choose for nesting sites are closed."
For additional information about raptor closures, please visit the Rocky Mountain National Parks area closures website.
This is an excellent and unknown route. Hike the Fern Lake trail for 1 and 1/2 miles to a bridge. Scramble up the hillside to the right; the Colossus is a dome with its east side seemingly shorn off, left of a prominent, orange prow. The walk is long enough to induce one to do other routes in the area as well.
P1-just up from the SE corner of the Dome, find a clean, 100 foot long vertical hand crack--classic 5.8. Belay on the ridge.
P2-climb steep and blocky but flawless rock above the belay (5.8 R), and continue more easily up nice cracks to the top.
