Okay, we’re here in the Grand Canyon, on the
Trail of Beaver. The park does a lot to get rid of this plant,
but, so do beavers. This stick they have detached, and chewed
off. And over here you can actually see a trail
of the beaver. This is there tail drag right here, and there
footprints as they came up to get at this Tamarisk, and chew it off and go back down
to the river.
