Screen Washing with Minty!

Ever wonder what happens when an excavation team misses something while digging? The answer is... screening!

Each digger collects her soil into a bucket, which is tagged with a number matching its location. The buckets are each sifted through a stack of three screens. Each screen gets progressively finer, so large pebbles are in the first screen, medium gravel is in the second screen, and fine particles are in the third screen.

Minty is posing with some gravel from the second screen.

After screening, gravel is taken to the lab, where significant items are sorted out. These include everything from mammoth bone fragments to rodent teeth. Miniature fossils!
