Named [informally?] for exposures in Canyon Range of central UT, Millard and Juab Cos, Great Basin province. No type locality designated. Consists of 10,000 ft of red-matrix boulder conglomerates, conglomerates, and sandstones, with local lacustrine limestones. These rocks formerly assigned to Indianola? conglomerate by Christiansen (1952, G.S.A. Bull., v. 63, p. 717-740). Occurs with angular unconformity across a major thrust which locally has placed it in contact with Eocambrian quartzites. Age of unit is now well known; author suggests Canyon Range may be lateral equivalent to Flagstaff Limestone (Paleocene and early Eocene age) of Utah Plateaus, however, unit may correlate with upper part of Indianola, though Price River age or younger is more likely.

Canyon Range Formation is applied to rocks formally assigned to the Indianola Group (Christiansen, 1952), and later called the informal Canyon Range formation (Stolle, 1978). Unit is informally subdivided into lower, middle, and upper members as defined by Christiansen (1952). The lower member, equivalent to the lower part of Stolle's (1978) unit A, consists of coarse conglomerate that has Paleozoic limestone clasts in a red matrix, and ranges from 265 to 414 m in thickness. The middle member, equivalent to the upper part of Stolle's unit A, consists of a resistant quartzite clast conglomerate that has a red sand matrix, and ranges from 125 to 600 m in thickness. The upper member, equivalent to Stole's unit B, consists of more that 1200 m of cobble and pebble conglomerate, coarse sandstone, siltstone, shale, and nonmarine limestone. Unconformably overlies Late(?) Cambrian carbonates; unconformably underlies the Tertiary red beds of Wide Canyon. Age is Cretaceous and Tertiary. (B1565)
