Glacier Movement Animations and Interactives
Here's another resource related to valley (alpine) glaciers created by the PhET (?) project. The PhET™ project at the University of Colorado provides interactive, research-based simulations of physical phenomena for free. Check out this Glacier Simulation (select "run now") and then browse through their other Earth Science-related simulations

Below: Speaking of glacial movement, this 48-second segment from NOVA shows 5 months of ice-flow from BENEATH Mt. Blanc in the Alps.

SNOTEL Sites Monitor Snowpack in Mountains
It's important to keep track of how much snow is present in the mountains because spring and summer runoff has an impact on irrigation, fishing/guiding, wildfire tendencies, hydropower, flooding, and other aspects of life in western states. SNOTEL (SNOwpack TELemetry) sites are automated stations that measure how much snow has fallen in remote mountainous areas. The system is operated by the Natural Resource and Conservation Service.
SNOTEL data are used to make management decisions regarding reservoirs (flood control, etc.) - Click on the map to make it bigger, and you will see that there is A LOT of snow in the mountains of western Montana right now (April 4, 2014). CLICK HERE to learn more about the SNOTEL System, and then check out the Interactive Montana SNOTEL Map to find out how much snow exists at each site.

Craters of the Moon Animation
CLICK HERE to view the animation.
This recent volcanic activity at the Craters of the Moon is thought to be caused by "leftovers" from the hot spot that currently sits beneath Yellowstone Park. In fact the Snake River Plain IS the path of the hot spot* over the past 15 million years. To learn more about the geologic past of this area CLICK HERE.
Another interesting aspect of the hot spot is the impact it had on ancient rhinos in Nebraska - CLICK HERE to learn more about that chapter in the geologic story of the area.
*Actually, it is the North American Plate that has been moving over the stationary hot spot.
