Afternoon storm risk is the line that matters. Everything else is comfort. In summer, plan to be off the ridge before the build-up starts, not as it starts. Forecast for the summit point, adjusted for its elevation · data from Open-Meteo.
Colorado 13er · East Ridge from UN 13,291
Overview
UN 13,220 lies at the head of the North Fork of Lake Creek, looking down on Marten Creek and the Fryingpan's South Fork, with a distant view of the Williams Mountains.
From UN 13,291 you go back to the saddle (the only Class 3 part) and follow the ridge south and west, Class 2+ at most, often past snow cornices early in summer. A ramp on the left bypasses the rocky summit block.
The loop with UN 13,291 is about 10 miles with 3,350 feet of gain. On its own from the North Fork it's a Class 2 climb.

Route-finding
Moderate. At the base of the summit block, look for the ramp to the left (southwest).
Water
North Fork Lake Creek and Lackawanna Gulch. Filter it.
From Aspen, drive east on Highway 82 over Independence Pass. On the east side, just below the final switchback as the road comes down into the North Fork Lake Creek valley, turn left onto a short dirt road to a small lot with a wood rail fence, just under 5 miles below the top.
From US 24, take Highway 82 west past Twin Lakes up the Lake Creek valley about 18.5 miles; the turn is on the right just before the first big switchback. Any car can make it. Camping at the lot is poor; there are campgrounds toward Twin Lakes.

The line is elevation, the band underneath is the ground, and the numbered dots match the steps below. Mileage and elevations are approximate.
1
North Fork Lake Creek trailhead 10,794' · 0 mi
Walk north on the trail. For about 3 miles it gains little, passing lots of willows.
2
Climb begins 11,200' · 3.2 mi
Past where the two main upper drainages meet, the trail climbs straight north up a broad slope beside a thin line of low trees. At a junction, go right; the left trail to Marten Creek is closed.
3
Unnamed lake 12,378' · 4 mi
Cross a small ridge and the line of trees and climb northeast, with a few switchbacks, to the lake below the Divide.
4
Ridge break 12,900' · 4.4 mi
Walk the west side of the lake to the pass, then leave the trail for a big couloir leading to the first break in the ridge to the west. Grass turns to rock and gravel.
5
UN 13,291 13,291' · 4.9 mi
Climb UN 13,291 by the east-side ledges (see that page).
Watch for: Class 3.
6
Saddle 13,050' · 5.2 mi
Retrace your steps to the saddle north of the Divide bend and climb about 200 feet south on small rock.
7
Point 12,990 12,990' · 5.7 mi
Follow the ridge south, then west near Point 12,990. Stay back from any cornices.
8
West saddle 12,700' · 6.2 mi
Keep going to the 12,700-foot low point west of UN 13,220.
9
Summit 13,220' · 6.5 mi
Climb the ridgeline east. Below the rocky summit block, take a ramp to the left onto open slopes and walk to the top.
Getting down
Go back to the 12,700-foot saddle and follow traces of the old Marten Creek trail southeast to the main trail, or walk down the southwest ridge, drop a short couloir, and make a long contouring descent southeast, through some willows, to the North Fork trail.
If things go wrong
The 12,700-foot saddle has an old trail down to the North Fork.
3D flyover
No 3D flyover for this peak
Past the lake the route is trailless ridge. A flyover only works when there is a set trail to trace. Without one, the line would be a guess, and a guess could send you the wrong way on the mountain. Use the step-by-step route with a good map and GPS track instead.

We haven’t found a good video of this route that matches the way we describe it. The route strip, junctions and 3D flyover show the way in the meantime.
This describes the route on a dry summer day. Most 13ers see few people, so there may be no one along behind you. Check recent conditions the week you go, carry a map, tell someone your plan, and turn around when the day tells you to.
