A former U occurrence/mine. Started in the early 1950's.
Mineralization is a weakly mineralized mass of the Shinarump member of the Chinle formation about 150 feet long by 50 feet wide. Mineralization is essentially the same as in the Monument No. 1 mine; however, only specific species attributed to this mine are listed.
Strata in the Monument No. 1 Annex are similar to those filling the Monument No. 1 channel except that light-gray oval clay pebbles, about half an inch long, are in a matrix of coarse-grained sandstone. The clay pebbles are so alined as to give an impression of rudimentary horizontal bedding. Yellow uranium minerals are disseminated in the interstices of the sandstone near the pebbles, but they are absent elsewhere. A banded appearance results: yellow mineralized bands about 1 inch wide alternate with white barren bands, also about 1 inch wide. Close examination near some of the clay pebbles indicates that in some, yellow uranium minerals impregnate the sandstone to the very edges of the pebbles. In others, a halo about a quarter of an inch thick devoid of uranium minerals surrounds them.
Trash pockets of fossil plant matter are common in the rocks of the Monument No. 1 Annex. These pockets appear in cross section as irregular thin strips of black coaly substance (vi train n. In plan view, these pockets show as impressions of reed-like plant material in the sandstone.
