J Plligers 1977 Journal Produde Bay, N. Slope, Alaska 24 July On down wind side we kicked up a dust storm with every step. Brief transect description: (1) runs through mixed polygons and ponds (old than 6). (2) emergent way along NE side of large lake running into upper well and with M2 filled low center polygons. (3) flat center polygons of M2, running past several lakes, (4) same. (5) rim of lacustrine fill extending out into peninsula or isthmus between two lakes. In general these are mesic upland and lowland wetland transects, and should be rich with C. pusilla during the breeding season. Blocks of Pluvialis dominica moved past toward the east as we set out the transect suggesting C. pusilla quit appearing over 100m. Talked w/ Kaye Everett about polygon formation: Once you have the ice wedge pattern [produced via the Lichenbrad model of derivation of virgin surface inducing polygonal cracking whose dimensions are determined by the parent material] the following sort of succession sets in: [diagram] (6) rims continue to grow due to ice-wedge growth, forcing material up + in if thermal erosion of ice wedge begins or thermokarsting due to various agents such as vehicular drawing, etc.: LCB [diagram] FCP [diagram] HEP [diagram] So the production of HEP is not due to increased height of center but rather the increasing depth of the troughs. Events is not willing to accept the flaw-like cycle anymore (the reason for oriented lobes in the coastal plain I was suspecting their orientation may be due to geologic fracture patterns in the bedrock, J. Brown scoffed at this notion. Kaye is predicting a bimodal distribution in an orientation of the long axis, with a minor peak 90° from the one so evident even to the untrained eye at ~90° from prevailing wind. 25 July spent entire day in field w/ Skip Walker, learning about this Produde vegetation scheme, learning what to look for in [illegible] identifying various plants, and being frustrated by others.
