Along the Black Flat Trail. I think this portion was actually re-routed, but it was prettier than just following an ATV dirt road. Mount Marvine visible top left, my first objective.

Along the remains of the ATV road.

Pretty tarns along the way.

Still along some old ATV remains.

View back as I continue along the Black Flat Trail.

Eventually the old trail merged with the maintained ATV trail that led me up to UM Pass.

Starting up to Mount Marvine.

Class 2 boulder-hoppping.

Mount Marvine ahead.

More boulder field hopping.

After making my way through the boulder field, I found myself on Mount Marvine's southeast slope. I located what seemed to be the least steep option up the Class 2 boulders.

View back toward the boulder field. Mount Terrill visible top left.

Class 2 to the ridge.

After gaining the ridge, I swapped over to Mount Marvine's west side. This is a view south as I continue along Mount Marvine's west side.

Along the Class 2 west side of Mount Marvine's crest. I headed all the way to its north end where I located a reasonable scramble option.

North side of Mount Marvine, I scrambled up this short Class 3 move to reach the summit.

Mount Marvine summit, view north toward Mount Terrill (top left). UM Pass visible center.

Mount Marvine summit, view south.

Mount Marvine summit, view east toward Hilgard Mountain. Also, my car is somewhere amongst the tarns in the center of this photo.

Back at UM Pass, I started toward Mount Terrill. This is a view back toward Mount Marvine.

Approaching the south ridge of Mount Terrill. I left the ATV road to ascend when the brush seemed less awful.

The initial ascent up Mount Terrill's south ridge swaps between light bushwhacking and Class 2 boulder fields.

View back, Mount Marvine visible in the distance.

Class 2 with some bushwhacking, but nothing too bad.


The terrain became a little easier. View back toward Marvine.

Along Mount Terrill's rim, where the terrain seemed to be a bit more brushy, but the views were nice.

Soon the trees and Class 2 pretty much faded completely and the rest of the ascent to the summit was more gradual and pleasant.

Ascending to Mount Terrill.

Just below the summit, view back toward my progress, Mount Marvine visible on the right.

Summit of Mount Terrill. The eastern cliffs (left side in this photo) are too steep to descend directly. I continued north to locate a reasonable way down.

View north rom Mount Terrill.

A social trail more or less helped me down from the north side of Mount Terrill.

View back toward Mount Terrill's summit, via the route I came down.

I continued east down to the saddle on Mount Terrill's east side.

Continuing down on easy terrain.

A short boulder field slowed me down before reaching the saddle.

View back along the boulder field.

The saddle visible in the center. Once at the saddle, I headed south.

At the saddle, a very old trail. I headed south.

Continuing south along a sometimes difficult to follow trail, but animals seem to have carved a route, making it pretty easy overall. Mount Marvine visible top right.

View back up toward Mount Terrill as I descend.

Heading back to the Black Flat Trail, which I took back to my car.
