Extraction of Ancient Pollen Grains
from Emigration Creek Sediments
Westminster College is home to sedimentary outcrops that capture over 4000 years of the post-Bonneville history of the Salt Lake Valley. The information in those outcrops is not just geological, but also botanical. Pollen from ancient plants was trapped in the sediments as they accumulated and have survived for millennia. Often, as in the case of the pollen grain shown to the right, the pollen is so well preserved that a botanist can identify the species of plant that made it.
