What is known as the “north star lower dumps” is a small dump located below the actual dumps of the mine. It appears to be an aggregation of multiple different mine dumps, and formed as a result of many years of erosion carrying the rocks down the canyon from both the boss tweed and north star mines, and possibly others. After many years of piling up, it appears as if a bulldozer was used to clear a path through the canyon, as there are are areas where it is flat, and appears to have been pushed into piles. It is easily recognized by a single tree which grows out of the dumps right next to the road.
The mineralogy of these dumps differ from that of the main north star dumps, being that it contains an abundance of arsenate, copper, and bismuth minerals such as mixite and azurite which occur together frequently.
