This shovel in Golden New Mexico isn't like any I've seen before. It looks built in place, hanging off the side of that structure, and not mobile. It appears it's shoveling dirt into a hole on the far side, where a series of scoops on a conveyer carry it up to the second level, dumping the dirt into the revolving screen drum. The drum would dump larger pieces like rocks out the chute on the near end, and the fine stuff is going somewhere else, perhaps a smelter.
They must be bringing the dirt to the shovel with wagons, trucks, or railcars.
