The Coyote Canyon Mammoth Dig is an active paleontological excavation site in the Horse Heaven Hills near Kennewick, Washington. It’s a significant project that sheds light on the history of the Ice Age floods in the Tri-Cities area.
The dig focuses on the unearthed remains of a Columbian mammoth that lived approximately 17,500 years ago. The mammoth’s carcass was buried in Touchet beds, a geological formation laid down by ancient floods. The site sits at an elevation of 1040 feet above sea level, which is considerably higher than the current elevation of the Columbia River, which is only 350 feet above sea level about 7 miles north.
Scientists estimate that Lake Lewis, a massive glacial lake that existed during the Ice Age, reached a maximum surface elevation of over 1200 feet above sea level at the time the mammoth perished. This substantial difference in elevation hints at the immense power of the Ice Age floods that swept across the region.
Another fascinating aspect of the Coyote Canyon Mammoth Dig is the discovery of a vast pile of erratic rocks. Initially thought to be a small cluster, the collection of these displaced rocks has grown to extend into several adjacent dig units. A dig unit, for those unfamiliar with archaeological and paleontological fieldwork, is a standardized square measuring 2 meters by 2 meters that archaeologists and paleontologists use to meticulously excavate and collect data.
The MCBones Research Center, a non-profit organization, spearheads the Coyote Canyon Mammoth Dig. They offer educational tours for schools and other groups, providing a firsthand look at this significant paleontological excavation. These tours are a great opportunity to learn more about the Ice Age floods, mammoths, and the meticulous work of paleontologists.
