A couple of weeks ago I decided to head back to the James Peak Wilderness Area for a hike. We did a backpacking trip in this area last summer up to Crater Lakes and I wanted to go back to explore more of the area.
On the way back, I had hoped to take another side trail and head up to Arapaho Lakes. Approximately 0.95 miles back down from lower Forest Lake was supposed to be another trail junction for Arapaho Lakes. This was one time I wish I had brought my GPS with me as I didn’t recall seeing the trail junction on the way up. I guessed by my hiking time when I thought I should be at the trail junction. According to some other trip reports I had read, the Forest Service decided to stop maintaining the trail to Arapaho Lakes and the trail sign had been removed. I did find what looked like a trail covered with branches. I headed down the trail a ways to Arapaho Creek. I couldn’t find a bridge or log crossing the creek and I scanned the other side for a trail but couldn’t find one. After exploring around a bit, I decided to skip trying to find the trail to Arapaho Lakes and headed on back down to the trailhead.
As I approached the parking lot, a train was just heading through the Moffat Tunnel.
I got back to the car around 1:15pm. Heading back down the Rollins Pass Road, I stopped to read about the Moffat Road. I debated heading up this 4-wheel drive road but decided to save that for another day. I also wasn’t sure what kind of condition the road was in and decided I wanted to research it more before attempting to drive up it.
I stopped along Highway 72 to take this shot looking back to the west of the James Peak/Indian Peaks Wilderness Area.
Heading back down Highway 72 through Wondervu, I decided to turn off the highway and check out Gross Reservoir. I’ve driven by the sign off of Highway 72 many times but had never been there. Gross Reservoir is owned and operated by Denver Water. The reservoir was completed in 1954 and serves as a combination storage and regulating facility for water that flows under the Continental Divide through the Moffat Tunnel.
Standing 340 feet above the South Boulder Creek streambed, Gross Dam contains some 627,559 cubic yards of concrete. Gross Reservoir has a surface area of 440 acres and 10.9 miles of shoreline.

After exploring Gross Reservoir, I headed back home. Another great day exploring in the High Country!
