Book excerpt: This report summarizes information on soil frost effects collected on Rocky Flats during the 1976 and 1977 winter. The work has continued on two scales as in the previous two winters. Empirical surveys along 4 line transects during the second half of the winter support earlier conclusions that the frost susceptibility of the Rocky Flats soils is well keyed to topography. This has been used in testing a mapping procedure for potential soil frost activity in the entire Rocky Flats area. Instrumental records of weather and soil conditions have been maintained throughout the winter at the Lindsay Ranch study site, northwest of the Rocky Flats Plant. During the winter, 9 frost heave events have been recorded and are described here. This represents a low frequency of soil disturbance by frost and is accounted for by the drought conditions on the Colorado Piedmont during 1976 and 1977. Even the events which occurred were of relatively slight magnitude, a further reflection of the lack of soil moisture during the period.
