Kayakers describe rock throwing near island on Keystone Lake

20 May 2009 after midnight, around 2:00 a.m. Shady Grove, Tulsa County, Oklahoma 2 witnesses

Account

Three people camped on an island area at Keystone Lake and heard repeated grunting and howl-like vocalizations after midnight. After two people kayaked back to the cars and two returned, the two in kayaks had two very large rocks land in the water near them as they approached shore in darkness. One had earlier seen green eyeshine near the campsite on the first return. Finding no other people on the island, they packed up and left during the night.
