Nature Series: Alpine Wildflower ID Hike to Alpine Tunnel

July 14 @ 7:30 am - 3:00 pm

This program typically takes place on Cottonwood Pass however the pass is currently closed for road construction. This year, participants will begin hiking in the ghost town of Hancock to the Alpine Tunnel following the old South Park & Pacific railroad grade identifying different species of wildflowers along the way. The hike is 6-miles roundtrip to the high end of the subalpine life zone where alpine and subalpine flowers overlap (ecotone). At the high end of the subalpine zone, we will see alpine flowers as well. The hike begins at 11,070 feet and reaches 11,600 at the tunnel entrance. Apart from the altitude, this is a gentle hike on a 4% grade. The wildflowers are usually spectacular, and the views are incredible.

The hike will be led by longtime GARNA volunteer Marilyn Moore. Marilyn was a Master Gardener in Denver County for 17 years and a horticulture volunteer at Denver Botanic Gardens for 20 years.

Information on meeting location, carpooling, etc. will be provided after registering. We offer this program every summer and it always fills up; we encourage you to register soon to reserve your spot.

The cost of the program is $10 for GARNA members; $13 for non members. Fees support coordination and promotion of GARNA programs.
