I found this on the UofO website. Turns out that the same site you are visiting is the same one that I heard through the grape vine at home... Patrick O-Grady also teaches at Lane Community. No wonder why this story struck a familiar chord! Hope you have fun...
"In 2010, the University of Oregon Archaeological Field School will return to the Sheep Mountain Clovis site, Paisley Caves, and initiate new excavations at Dirty Shame Rockshelter. The Sheep Mountain site is only the third in Oregon to produce multiple fluted points, documenting human activity at the late Pleistocene early Holocene interface.
The field school has been conducting research at Paisley Caves under the direction of Dr. Dennis L. Jenkins, who has supervised and directed the UO field school since 1989. Patrick O'Grady has been supervising operations at Sheep Mountain for two seasons."
