Red till diapir
In this image the trace of a thick diapir of red till is exposed in the side of the hole, and its surface trace is white, trending toward the upper left of the photo. In this region, diapirs are readily spotted by the white color that they assume as the red till dries out after it reaches the mudboil surface. Salts, to which caribou of the Kaminuriak herd seem to be attracted when they traverse this area on their way to calving grounds to the north, in the vicinity of Kaminuriak Lake, are commonly found as efflorescence on the white diapir surfaces. See images 0073 (same diapir as 0042), 0099, and 0216 for further examples of red till diapir traces for both air and ground views. See detailed discussion for image 0240.
