53 Tule Lake Tule Lk Tule Lake; N. California; There were five cores taken, four of which (#'s 1, 2, 3, 5) were looked at by J.P. Bradbury. They all came from about the same place and they appeared to correlate well enough on the basis of distinctive diatom assemblages to paste together into a composite stratigraphy. The data from this composite 'core' (Tule Cmp) is presented here. A species category was created to represent all the diatoms whose distribution was too spotty and whose percentages were too low to be of much value in paleolimnological interpretation. This is called 'Misc. low paleolim. value sp.' in the undetermined diatom genera category. J.P. Bradbury 296 1
