Museums hold 52 specimens collected within 10 miles of Canyon Park between 1901 and 1975: 41 Animalia, 8 Fungi, 3 Plantae. 12 distinct Species records are shown. Collected by B. J. Crandall, B.J.Crandall, C. G. Lloyd and others. Each is a physical object with a catalogue number, and each entry opens the museum's record. This is what was collected and kept, not a survey of what lives here - nothing can be concluded from a species being absent.
