What the map says
Unit commonly includes talus (Qt), colluvium (Qc) and other mass-movement deposits, rock-glacier deposits (Qrg), and till of Pinedale age (Qtp) near heads of glaciated valleys. Unit locally includes tills of the Satanta Peak and Triple Lakes advances of Benedict (1985), about 12–10 ka (Davis, 1988), and tills of Holocene age near cirque headwalls (Benson and others, 2007). Unit also locally includes rotational rock-slide deposits (Qls) derived from bedrock that is extensively faulted and (or) highly altered. Estimated thickness 3–50 m; possibly as much as 100 m in large rotational rock-slide deposits
