Welcome to Tolsona Creek to Matanuska Glacier
From Eureka Summit (Mile 129.3), the highway’s highest point (3222ft), you can see both Gunsight Mountain and the Chugach Mountains to the south. The Nelchina Glacier spills down in the middle here and the Talkeetna Mountains strut to the northwest.
From here the Glenn Hwy begins to descend, and the surrounding scenery fires the imagination as the Talkeetna Mountains loom in the distance and you pass the sphinx-like rock formation known as the Lion’s Head (Mile 114). A half-mile further, the highway reaches the first viewpoint of Matanuska Glacier. To the north is Sheep Mountain, aptly named as you can often spot Dall sheep on its slopes.
