Summary:
Pg. 121, pl. 1-b. Bellisle Mountain basalt or flow (in Clayton basalt). Ten basalt flows in what is termed the Folsom sequence of Clayton basalt are named and mapped. Stratigraphic position of six of these basalts has been determined. Bellisle Mountain is fourth in known sequence; younger than Mud Hill and older than Robinson Mountain. Consists of single flow 15 to 20 feet thick and with well-developed platy structure.
Bellisle Mountain [now called Dale Mountain] is a small volcanic peak on Johnson Mesa in northeastern Colfax Co., northeastern NM, about 10 mi west of Union Co.
