Earth Science Outdoor Laboratory

Earth Science students examining an outcrop of Pleistocene (Ice Age) flood deposits at Tammany Creek. Our location in north-central Idaho affords a fantastic natural laboratory for both natural science course work and student science research projects. These students are testing ideas regarding multiple floods that occurred on the Snake River as a result of repeated advances of the Canadian ice sheet to the north. Current direction indicators in the sedimentary layers give clues as to whether a given deposit resulted from flood waters travelling down the river from the Salt Lake basin, or up the river, resulting from flood waters issued from Glacial Lake Missoula that backed-up the Snake River system from the Pasco basin.
