Mount Ascension is a prominent 57100NaN0 mountain summit located in the Kenai Mountains, on the Kenai Peninsula, in the U.S. state of Alaska. The mountain is situated in Chugach National Forest, 6.80NaN0 south of Mount Adair, 3.50NaN0 north of Resurrection Peaks, and 100NaN0 north of Seward, Alaska. The peak is near the mouth of Resurrection River into Resurrection Bay. The name Resurrection, referring to the Resurrection of Jesus, is overused for nearby landforms on the Kenai peninsula, as the mountain to the immediate south is Resurrection Peaks. This Ascension name is a variation of the theme. Mount Ascension's name was proposed in 1968 by the Mountaineering Club of Alaska, and officially adopted in 1969 by the United States Geological Survey.[3] Access to the peak is via the Lost Lake Trail, and mountaineering skills are needed to reach the summit. In clear weather the immense Harding Icefield can be seen from the top. The first ascent of this peak was made October 6, 1968, by John Vincent Hoeman and his wife, Dr. Grace (Jansen) Hoeman.[4]
Based on the Köppen climate classification, Mount Ascension is located in a subarctic climate zone with long, cold, snowy winters, and mild summers.[5] Temperatures can drop below −20 °C with wind chill factors below −30 °C. This climate supports a spruce and hemlock forest on the lower slopes.
