I incorporated your information onto the main Alyeska page. Thanks-that could be a lifesaver for someone. Climber46
There is some debate in the local mountaineering community as to whether Point 3939 (labeled Mount Alyeska on the USGS maps) is the summit of Mount Alyeska or whether Peak 4423 to the east is the true summit. Peak 4423 has been referred to as both True Summit and the True Summit of Mount Alyeska. It is now officially known as Hibbs Peak.
The glacier west of Point 3939 is the Alyeska Glacier.
Because the mountain is actively used as a ski area during the winter and spring, avalanche control is required. Avalanche control results in using mortars to shoot the mountain in an effort to bring down the heavy loads of snow. Sometimes these mortars do not explode on impact and can be found when the snows melt in the summer months. DO NOT TOUCH ANY MORTARS and, if found, report their locations to an Alyeska Ski Resort employee.
The ridge above the tram has shrapnel from these mortars all along the route to Point 3939.
