A petrified wood occurrence located 10.2 km (6.3 miles) SSE of Rotten Bananas Butte (coordinates of record).
Mineralization is a petrified wood deposit in unusual colours hosted in the Triassic Chinle Formation. Bright green petrified araucariae (probably coloured by chromium) are unique to this locality.

|Young flood-plain deposits|
Age: Anthropocene (0 - 0.0117 Ma)
Description: Gray-brown clay, silt, and fine- to coarse-grained sand; weakly consolidated by clay content. Forms benches 1 to 3 m (3 to 10 ft) above stream-channel (Qs) or modern flood-plain (Qf) deposits. Subject to cut-bank channel erosion in Little Colorado River Valley and local streams in large tributary washes. Overlapped by thin accumulations of young surficial deposits (Qd, Qes, Qps, Qa1). Supports thick growths of salt cedar (Tamarisk) trees, grass, tumble weed, camel thorn bush, and various other high-desert shrubs. Often subjected to overbank flooding by Little Colorado River and local tributary streams. Thickness, 1 to 6 m (3 to 20 ft)

Age: Late Triassic (208.5 - 237 Ma)
Stratigraphic Name: Chinle Formation
Description: Colorful mudstone, such as in the Painted Desert, and less abundant lenses of sandstone and conglomerate, deposited by a large river system. This unit typically is eroded into badlands topography and contains clays that are prone to shrinking and swelling. (210-230 Ma)
