Glacial Contribution to Stream Flow

Figure 14 lists the annual amount of runoff from the glaciers monitored. It is interesting to note that the amount the glaciers melt varies by as much as 50% from year to year. Furthermore, the glaciers provide a greater amount of water during years when snow pack is minimal. Thus, glaciers buffer streams, lakes and wetlands from droughts.

Grizzly bear tracks can be a reliable indicator of species? Grizzly bear and black bear forepaw tracks are distinct from one another and often times better than a photo of the bear to confirm an observation. So don't just look up, look down.
