LoDaisKa Site, Archaeological site in Morrison, Colorado.

The LoDaisKa Site is an archaeological dig location in the Rocky Mountain foothills where researchers found evidence of ancient occupation beneath and beside a large rock shelter. The terrain shows the landscape these early inhabitants knew and used for survival.

Excavated in the 1950s by Cynthia C. Irwin and Henry Irwin, the site yielded artifacts spanning roughly 3000 BC to AD 1000, which they divided into five complexes labeled A through E, with E the oldest. Radiocarbon dating reported in 1961 confirmed this long occupation. In 2003 the site (5JF142) was listed on the National Register of Historic Places.

Excavations by Cynthia C. Irwin and Henry Irwin assigned the finds to five complexes, A to E, with E the oldest. Later Archaic layers held corn and cord-wrapped pottery for storing food, and Complex D produced seven lumps of red and yellow ochre, possibly paint stones.

The rockshelter sits in the foothills off U.S. Route 285 near Morrison, at about 6,200 feet (1,900 m) elevation, beneath a 60-foot red sandstone overhang of Fountain Formation rock. The site is listed on the National Register of Historic Places as 5JF142, so the deposit is protected; approach on foot and leave the shelter floor and any exposed artifacts undisturbed.

Researchers found objects here that rarely survive in ancient layers, including wooden tools and animal hides. These unusual discoveries reveal how skilled these early people were in making and using everyday items.
