Air-Powered Excavation Spade
Descriptive Transcript
The high pressure air from the tool makes a consistant whooshing sound as the operator directs it towards the soil.
Description
A high pressure stream of air from the air-powered excavation spade is carefully directed around the base of a tree in the national cemetery at Little Bighorn Battlefield National Monument, forming trenches that extend outward from the trunk. This loosens the compacted soil around tree roots, improving the flow of air, water, and nutrients and improving the overall health of the tree. Note the protective equipment and the archeologist monitoring the process.
