Representative Deglacial paleohydrologic records from western North America. (a) North Greenland Ice Core Project (NGRIP) oxygen isotope record48. (b) Areal extent of North American ice sheets70. (c) North Atlantic core OCE326-GGC5 Pa/Th (AMOC intensity)65. (d) Lake Chewaucan lake level and 14C ages, Abert sub-basin (blue) and Summer sub-basin (orange) shown separately. (e) Lake Surprise lake level based on 14C dating (green line; dashed where uncertain)44. (f) Lake Franklin lake level (pink, 14C ages in pink circles)52. (g) Lake Lahontan lake level (red, minimum limits on lake level red circles, maximum limits on lake level triangles)53. (h) Lake Elsinore percent sand-sized sediment (gray; proxy for watershed runoff)4. HS1 (18.0–14.6 ka) interval shown by blue bar, divided into HS1a (18.0–16.1 ka) and HS1b (16.1–14.6 ka) by dashed line. B/A interval (14.6–12.8 ka) shown by orange bar.
