Geology
Tanada Peak is the erosional remnant of Tanada Volcano which was an andesitic shield volcano which probably began forming 1.5 million years ago, with the last eruption occurring 970,000 years ago.[1] Prior to one million years ago, the shield collapsed, forming a caldera. The peak is now the high point within a caldera measuring four miles (6.4 km) by six miles (9.7 km). An unnamed glacier in the caldera on the peak's southwest slope is a small remnant of the much larger glaciers that once covered the volcano and carved away much of the 400 km2 (154 square miles) shield.[1]
Climate
Based on the Köppen climate classification, Tanada Peak is located in a tundra climate zone, with long, cold, snowy winters, and cool summers.[9] Weather systems coming off the Gulf of Alaska are forced upwards by the Wrangell Mountains (orographic lift), causing heavy precipitation in the form of rainfall and snowfall. Winter temperatures can drop below -10 °F with wind chill factors below −20 °F. This climate supports an unnamed glacier and permanent ice surrounding the peak.
