Avalanches are most common during the winter, December to April in the Northern Hemisphere, but they do occur year-round . To get an avalanche, you need a surface bed of snow, a weaker layer that can collapse, and an overlaying snow slab. The highest risk period is during and immediately after a snow storm.

Very steep, extreme terrain is especially unfavourable as regards the slope angle, topography, proximity to ridgelines or ground conditionsextremely steep: steeper than 40°very steep: steeper than 35°steep: steeper than 30°moderately steep: less than 30°.

How fast does an avrage rocket travel?
This maximum speed is 670 feet per second or about 3.5 times as fast as the average speed. How does a rocket travel to low Earth orbit? The speed required for LEO (Low Earth Orbit) is abput 17,500 mph. A rocket launched vertically must reach this speed by the time the payload, typically a crew capsule or a satellite, is released. So the rocket accelerates from zero to this speed in about 8 and 1/2 minutes.
