Woon, Jr., Ross B. JoHNSON and GEoRGE H. DixoN ABSTRACT The part of the southern half of the Spanish Peaks quadrangle described in this report has an area of about 245 square miles. It is part of the Trinidad coalfield in the Raton Mesa region of southeastern Colorado, and extends from longitude 104°30'00" on the east to longitude 104°52'30" on the west and from the Colorado­ New Mexico boundary line (approximately 37°00'00") on the south to latitude 37°10'00" on the north. Most of the area is in the Park Plateau subsection of the Raton section of the Great Plains physiographic province, the rest, near the town of Trinidad, is in the Chaquaqua Plateau subsection. The area lies on the eastern limb of the Raton basin, a large, complex, and asymmetric structural depression that extends northward from the vicinity of Las Vegas, N. Mex., into Huerfano Park, southern Colorado, and lies between the north-trending Sangre de Cristo Mountains on the west and the northeasterly trending Sierra Grande arch on the east. The approximate axis of the basin lies a few miles to the west of the report area near the foot of the Sangre 'de Cristo Mountains and its general trace roughly parallels the axis of the range. The Raton basin was formed during the latter part of the Laramide revolution (Eocene epoch) by the same compressive forces which produced the eastward thrusting in the Sangre de Cristo Mountains. It is, in a regional sense, an overturned syn­ cline, the western limb having been largely removed by erosion and the eastern limb having been irregularly downwarped into series of long, narrow, north-trending folds. Structural relief of these folds seldom exceeds 200 feet. A prism of sedimentary rock in the Raton Mesa region may be 10,000 feet thick in the eastern part of the area of the report and may thicken gradually to as much as 25,000 feet in the western part.
