Hike Overview
      While unnamed 12505A is an official Colorado peak it is rarely ever climbed. This peak shares a ridge with the very popular 14er Mt Yale. The Colorado Trail passes right between them. This short hike from the segment highpoint is an easy class 1 hike.

Hike Details
      This hike is a mere 1.50 miles round trip from where you leave the Colorado Trail Segment 13 highpoint. What's more, it's only an additional 585 ft of elevation gain from the highpoint. Expect on average about 1 hour to make the round trip. As you reach the trail highpoint the summit of UN12505A is just off to the east. Looking east you can see 12505 with it's small false summits:

 There is not always a really obvious trail over to this summit but its an easy ridge to follow.

Along the way look carefully for this old cabin/mine:
