<br />2892 <br /> <br />The thickness of the Salt Wash differs greatly in the <br /> <br /> <br />. project ~rea, owing to intertonguing and gradation with <br /> <br /> <br />adjacent units. In the McElmo Canyon area the Salt Wash is <br /> <br /> <br />100 to 250 feet thick. In the central part of the Carrizo <br /> <br /> <br />Mountain area, the unit is 180 to 200 feet thick (Strobell, <br /> <br /> <br />1956), and farther south near Toadlena, N. Mex., it can no <br /> <br /> <br />longer be recognized (Harshbarger, Repenning, and Irwin, <br /> <br /> <br />1957, pI. 3). <br /> <br /> <br />In at least one outcrop just south of the east toe of <br /> <br /> <br />the Ute Mountains, the Salt Wash is not present (Ekren and <br /> <br /> <br />Houser, personal communication, 1962), and the Recapture <br /> <br /> <br />Member lies directly on the Junction Creek Sandstone. <br /> <br /> <br />The Salt wash also is missing 20 miles west of the Ute <br /> <br /> <br />reservation, and the Recapture Member lies directly on <br /> <br /> <br />the Bluff Sandstone (Junction Creek Sandstone in Colorado). <br /> <br /> <br />The Recapture Shale Member of the Morrison Formation <br /> <br /> <br />intertongues with and grades into the Salt Wash, and the <br /> <br /> <br />unit is not everyWgere recognizable in the northern part <br /> <br /> <br />of the reservation. Ekren and Houser (1958, p. 75) report <br /> <br /> <br />that it is absent in eastern McElmo Canyon. The Westwater <br /> <br /> <br />canyon intertongues with and grades into the Brushy Basin <br /> <br /> <br />Member. It is thin in the northern part and probably is <br /> <br /> <br />not recognizable a short distance north of McElmo Creek. <br /> <br />. <br /> <br />. <br /> <br />L-.z <br />
