Greasewood Springs AZ: Cylindrical UAP at Satan's Butte, BAASS On-Site Investigation
On the evening of 1 June 2010, schoolteacher Bryce Kimmer was stargazing outside his home in Greasewood Springs, Arizona (Navajo Nation) when he noticed an unusual object near a prominent local landmark known as Satan's Butte, approximately three miles west. The object appeared to fly directly into the rock formation. The sighting repeated on 3 June — when both Kimmer and his wife observed it — and again at 22:46 on 9 June 2010. Kimmer described the object as a cylindrical sphere with red blinking lights.
BAASS investigators Larry Grossmann (Chief of Investigations) and Leon Campbell, PhD (Senior Scientist) traveled to the area 12-15 July 2010 to conduct a field investigation alongside Navajo Rangers Lieutenant Jonathan Dover and Sergeant Stanley Milford Jr. The team took comprehensive environmental readings using professional-grade instruments: a Garmin GPS Oregon 400t for positioning, a Canberra radiation detector (alpha, beta, gamma), an RF spectrum analyzer (100 kHz-9.4 GHz), and a Thermo Scientific NITON XRF analyzer for soil composition. All readings were within normal parameters — slightly elevated barium and strontium were considered typical for the regional geology.
