Several magmatic dikes radiate out from the mountain, and some are visible from Colorado State Highway 125, which goes over Willow Creek Pass just west of Radial Mountain.[5]
Hiking
Radial Mountain is among the most accessible to hike in the Rabbit Ears Range.[3] It's close to Willow Creek Pass, where the Continental Divide Trail passes the highway. The trail doesn't go to the peak's summit, but it brings hikers partly there, then from that point, one can hike through the trees to the summit.[6]
