Pollen analysis.

Processing of a total of 49 samples from both a block of sediment from just within Marmes Rockshelter spanning roughly the last 11ka (see Sheppard et al., 1987) for both charcoal, pollen and acid resistant algal analysis began with placing 2 level tablespoons (27.6 cc) of sample in a 400 ml beaker with 75 ml of triple distilled water. For statistical purposes 4 Lycopodium tracer spore tablets (batch number 124961 with 12,542 spores per tablet) were added to each sample for a total of 49,984 spores per sample (Table 1).
