Traveling over the Mirror Lakes Highway, one can't help but notice Mount Agassiz, a large bulky mountain taking up much of the eastern skyline. Because of it's close proximity with the highway and it's 1,018 feet of prominence, the mountain is climbed often. A mailbox register on top testifies of the many, many ascents.
Distance: 3 milesish
Elevation Gain: 2,850 feet rt

From Kamas, head east on State highway 150, (Mirror Lake Highway) for 33 miles to Hayden Pass. Turn right into the hikers parking lot.
Start walking the Highland Trail. Unfortunately, the trail will drop some elevation. Within the first mile, another trail will branch right. After passing, continue another 5 or 10 minutes before taking an east baring and heading cross country toward the mountain. This is the fastest way. Others have hiked the Highland trail much further, eventually branching off to climb but it will take longer. The cross country isn't bad, just some logs and creeks to hop across here and there. When you reach the base of the mountain, the trees end and you can see a route north of all the cliffs of the west face. This gully is steep but the footing isn't too bad. Reach the ridgeline and continue up the northwest ridge to the summit.
