Welch Ditch Trail

RMOTHG Trip – Welch Ditch Trail

This trip is changed from Flying J Ranch due to muddy conditions. The meeting time is changed to 9:00am. This hike is limited to RMOTHG members only. Starting at the west end of Golden, we will hike at a gentle pace along the scenic Clear Creek Peaks to Plains trail, then along the Welch Ditch Trail above the creek. The four-mile round-tip trail is paved on the first part with an easy dirt trail along the old water and flume route (depending on trail/mud conditions, some additional portions of the trip may be on the paved path). The trail follows the creek through for two miles just past Tunnel 1 on US 6.

Hiking – Decatur Mountain via Shelf Lake

This hike is about 9 miles with 2800' elevation gain. We'll follow the Shelf Lake Trail to beautiful Shelf lake, and then ascend Decatur (12,890'). After gaining the summit, we'll return the way we came. We'll see Argentine Pass to the north along with handfuls of 12'ers & 13'ers to the N & S. Hopefully wildflowers will be blooming too.

Single Tall Pole – Mt Galbraith

This clinic will cover the basic techniques for improving your efficiency ascending and descending on trails and peak climbs using a Single Tall Pole (STP). The STP enables you to reduce impact on joints, reduce excess muscle strain and eliminate the damaging plunge step. You will feel the enhanced stability and balance as the STP enables you to concentrate on effective solid foot placements (i.e., better traction), which makes your backcountry travel easier, safer, and more enjoyable.
