Fireweed in bloom at Spencer Glacier, Alaska. Spencer Glacier is accessible by train via the Alaska Railroad and is the first of several whistle stops planned by the forest service. Activities include camping, hiking, or a float tour. The train drops you off at the whistle stop at 1:45pm and picks you back up at 4:40pm. You don’t want to miss the train. This day I wanted to hike to the end of the trail that was 3.1 miles from where the train drops you off and I had hustle to make sure I didn’t miss the train after the 6.2 mile roundtrip. Beautiful day!
