Belts of kames havingthe general position, relations, and significance of terminal morainesare called kame Kames occasionally attain a height of100 feet or more, but heights of 20 to 40 feet are much more stratification of the sand and gravel of which the kames are. Fig. 499.—A group of kames shown in contour; near Connecticut Farms, N. J. (N. J. Geol. Surv.) chiefly composed was often irregular at the outset, and was subjectto disturbance with every movement of the edge of the ice, so longas the ice and kames were in contact. The effects of the crowdingof the ice are often distinctly seen in the disturbed and crumpled con-dition of the planes of stratification. The stratification was subjectto still further disturbance when the ice melted, for in many cases 1 Rept. State Geol. of N. J., 1892, p. 93, and Glacial Geology of N.

Much of the material entering into the make-up of kames had not been carried far, and was, therefore, not well water-worn. Not rarelyits constituents retain glacial striae. These characteristics of thematerial of kames gave rise to the descriptive designation hillocksof angular gravel and dist
