Northwest Waterfall Survey of
- Racehorse Creek thunders over a great waterfall situated within a short, shallow and very interesting gorge. The falls drop a total of 139 feet over four distinct steps. The first two tiers are back-to-back punchbowl-type plunges of 19 and 44 feet respectively, which both feature deep potholes at their bases. Immediately below the second tier the creek accelerates down a ramp-like cascading fall for about 15 feet and then comes to the final drop where it first plunges over an undercut ledge and then slams onto a diagonally pitched bedrock ramp and veils out in a broad sheet, with a small pool on one side about three-quarters of the way down and ending in a much larger pool. The basin at the bottom of the falls is held back by a second diagonally pitched ramp of bedrock, within which is another small fall of about 10 feet.
- Urubamba River (Wikipedia)
The Urubamba River or Vilcamayo River (possibly from Quechua Willkamayu, for “sacred river”) is a river in Peru. Upstream it is called Vilcanota River (possibly from Aymara Willkanuta, for “house of the sun”). Within the La Convención Province, the name changes to Urubamba. A partially navigable headwater of the Amazon River, the Urubamba rises in the Andes to the southeast of Cusco. It originates on the slopes of Cunurana in the Puno Region, Melgar Province, near the La Raya pass. It flows north-north-west for 724 km (450 mi) before coalescing with the Tambo River to form the Ucayali River.
