Alaska Trail
The Alaska Trail is the northernmost trail of the Klondike Bluffs system. It must be reached via other trails, making the minimum loop ride 6.5 miles. The trail is upper-intermediate technical with moderate climbing. It's about half slickrock. Associated trails Nome and Homer provide variation on the rides. The top of Alaska is where Mega Steps turns from the ridgeline to descend.

Northern Klondike TH: On Highway 191 8.5 miles south of I-70 and 6.5 miles north of the southern Klondike Bluffs road (about 5 miles north of the airport), watch for a "Northern Klondike" sign at N38 49.504 W109 46.893. Turn east (toward the sandstone bluff). Keep to the right as the road winds south around a small hill. 1.2 miles from the highway as the road is heading east toward the bluff, fork right on a fainter jeep road N38 49.103 W109 46.061, as the main road continues to the dinosaur tracks. (Park here if the road is in bad shape.) At mile 1.6, you'll come to the TH for the Jasper and Agate loops (N38 49.087 W109 45.625) on your right. At 2.0 miles, you're at the bottom of Mega Steps at a larger parking area N38 49.179 W109 45.417. To reach Dino Flow, head uphill on Mega Steps .
Dinosaur Tracks TH: At the trail fork at mile 1.2, keep left on the main road toward the dinosaur tracks. About 1/2 mile further, turn to the right into the parking area. The Dino Flow trail is up against the mountain, to the left of the pit toilet.
Southern Klondike TH: Starting at the Colorado River, drive 15 miles north from Moab. Look for a turnout with parking on the right and a sign for Klondike Bluffs Road. There will usually be cars parked there (GPS N 38° 44.452' W 109° 44.037'). For a longer ride, park here and ride up the road.  Most cyclists will choose to go through the gate and drive 2.7 miles. Keep left at the fork. At 2.8 miles, park your car in the broad parking area by the fence. Go eastbound across the cattleguard through the fence and begin your ride. To reach Alaska, you'll need to pedal several miles north on Copper Ridge Road, Dino Flow, or EKG. Or, you can climb Baby Steps to Mega Steps and ride the ridge to reach Alaska at the top.
