P.A. Kelley 1986 Journal. June 30 (cont) 2119 PST Searched the U. Spring for fluor- escent trails with the black lamp. Fresh urine marks are also fluorescing a greenish color. Found orange pig from σ 2179 on the W. end of the rockpile. Found more of 2179's pig toward the middle of the rockpile - smeared on the angular tip of a rock. Looks like deliberate marking (w. Ventral gland) as in previous case. Found a succession of 2179's marks and all were along the most dorsal edge provided by the rocks in each case. Found 2179's den I think big 'hole' in rocks behind one of the big, central Arches on the upper E. side of the rockpile. Rocks in front of the den are completely smeared with orange pig. Also lots of fresh urine. Found more of his pig through- out the W. side of the U.Spring, again mainly on dorsal-most edges. 2148 Pig from ♀ 2186 (Red) and ♀ 2177 (Green) was confined to areas of capture and release. 2149 PST at the h. Spring found green pig from ♀ 2187 along the N. side of h. Spring especially at capture and release points. I also however found a little orange pig from σ 2179 in 3-4 places adjacent to ♀ 2187 trail.
