[3] The presence of Precambrian and Paleozoic clasts at the base of the Galisteo Formation suggests that the discontinuity separating it from the Diamond Tail is tectonic in origin.

[4] There are indications the formation itself experienced penecontemporaneous deformation, possibly due to renewed uplift of the southern Sangre de Cristo Mountains.

[3] Paleocurrent directions indicate the sources of the sediments deposited in the formation came from the Brazos-Sangre de Cristo Geanticline to the northeast and the Nacimiento Mountains to the northwest.

[5] The presence of Precambrian clasts in the upper part of the formation in the San Miguel Mountains was some of the first evidence for the existence of the Pajarito Uplift, a Laramide structure occupying what is now the southern Espanola Basin between the current locations of Los Alamos and Santa Fe that later foundered into the Rio Grande Rift.

He named the formation the Galisteo sand group and noted that its sandstone beds dipped from 5 to 50 degrees and varied in color from off-white to brick red.
