The high terrain on this cache is just for the fact that you may need to go wading to get this cache(depending on the water levels and time of year).
This earthcache is about the geology of Western Corridor Rivers and how they have influenced the flora and fauna in the west.
Most western corridor rivers form when small mountain or desert streams meet to eventually form large rivers. These rivers then cut valleys through the mountains. Eventually they reach the ocean. When compared to Eastern chalk streams we find that these rivers are more rocky, mainly because the bulk of the western US was formed by tectonics or volcanism. In our area this rivers flood each spring (or at least as much as they can with the dams) as an effect of the snowmelt in the Sierras. Also, the snowmelt from the mountains washes down large amounts of slit that builds u at certain locations, like this one. At this location you can observe effects of the flooding.
These are called corridor rivers because they are a corridor for salmon to run up on their way to spawn. This river is closed from November 1 to December 31 to protect the spawners at this location.
To get cedit for this earthcache:
1. The GC code and name of this cache.
2. The number of people in your group.
3. What kind(s) of salmon still run up this river?
4. Based on the signs of erosion and slit buildup from upstream, did the island at this location used to be bigger or smaller?
**NOTE**
This river is closed from Novenber 1 to December 31 to protect spawning salmon, so if you are doing this earthcache at that time just do the best you can from shore.
