Wolf Eagle, where this slide occurred there is not a forrest only slide alders. This area has always been an active slide zone. In 1962 a huge powder avalanche there ripped off many homes roofs in the wee hours of the morning. 
As for "clear cutting" I note that native corporations have excelled in that practice. Find Hobart Bay or Cube Cove or Long Island or even Whipple Creek on Google earth. 50 thousand plus acre cuts. Logs are loaded into ships and sent to the land of the rising sun. Young trees grow back immediately and so thick that they choke out any light to the forrest floor below. These areas are a dead zone for life since these corporations rarely thin out the new growth. So for 150 years there isn't habitat for wolves or eagles or anything else.
