 of faulting. Beds are approximately horizontal, but in one place on escarpment the thick conglomerate shows a decided dip to SE. However it appears to have pitched forward into that position. W of camp there is a decided unconformity between the thick conglomerate and the marl. At first sight this seemed possibly the result of the conglomerate pressing into the soft mud, but the strata above continuing unbroken and straight vetoes this idea unless the boulders and gravel pressed in as they were deposited ((drawing in field book)). At the NW (lefthand end of section) conglomerate rapidly passes into marl, not by thinning out, but by intercalation of strata of marl between narrow strata of conglomerate. Here as elsewhere, the line dividing the conglomerate from the underlying marl is abrupt, no gradation. The two places in above section marked by circles are occupied at base by boulders. In many places the conglomerate as
