(mm 2624) You just crossed over to the west side of Harts Pass Peak. The trail now points directly at Slate Peak and the fire look out that sits upon it. It is 3.8 miles away and 1,110 higher.
At 7,440′, Slate Peak Lookout is the 2nd highest fire lookout in Washington State located at the end of the highest road in the State. (The highest is on Mt Adams and is in ruins).
In 1924 the lookout was first constructed as a gable roof cupola.
In 1926, the top 40′ of Slate’s summit was blasted away by the Department of Defense to prepare for a WWII radar station that was never built.
In 1954 this new lookout was moved here from Leecher Mountain. It matched the height of the original 1924 lookout.
The lookout is off limits for visitors, but views from its feet are spectacular.
