Boulder

I have it from a very reliable source that there are at least two major waterfalls on this run between Boulder Falls and Highway 530. The first, called Corkscrew Falls, slams onto a bench halfway down, and is said to be almost 50 feet tall. The second, apparently, just under a mile from Highway 530, is called Half Mile Falls, and drops at least 30 feet, at roughly a 70 degree angle, into a huge pool (it may be runnable). Boulder Falls is unrunnable.
