OverviewUN13,722 "Lightning Pyramid" is located in the Elk Mountains 0.45 miles south of Thunder Pyramid just outside of Aspen, Colorado. Thunder Pyramid is a centennial thirteener coming in at 65 highest in the state, whereas "Lightning Pyramid" is a bicentennial thirteener coming in at 137. Thunder Pyramid and "Lightning Pyramid" both lie on Pyramid Peak's long south ridge. The summit offers great views of Pyramid Peak, South Maroon Peak, North Maroon Peak, Thunder Pyramid and UN13,631.Maroon Peak, Pyramid Peak and North Maroon Peak. "Lightning Pyramid" is recommended only for experienced climbers due to rotten rock and time-consuming route finding. "Lightning" is most commonly climbed via Thunder Pyramid's South Ridge outlined in Roachs' Colorado Thirteeners. However, "Lightning Pyramid" can also be climbed from UN13,631 via an interesting ridge traverse. UN13,631 is a bicentennial peak coming in at 180.

From Maroon Lake TH, hike southwest towards Crater Lake and take the left fork towards West Maroon Pass. Leave the trail at 10,600, climb east, then southeast on talus and grass to the broad basin west of Thunder Pyramid and "Lightning Pyramid". You will encounter cliff bands. Gullies allow progression up towards the basin. Continue to the basin's head. Climb left up a talus slope to the 13,300' saddle north of UN13,631. The climb south UN13,631's summit takes longer than one would think due to the ridge steps. The steps can be climbed or bypassed by staying on the east side of the ridge. Descend back to the saddle and continue to "Lightning Pyramid". There are many obstacles to avoid, but most of the climb is class 2+ with much route finding and loose rock avoidance. Stay to the right (east) side of the ridge to avoid difficulties. Descend the south ridge or continue north to Thunder Pyramid.
