- The Lummi River is the current name for a river channel that was, prior to the beginning of the 20th century, the main outflow channel for the Nooksack River. It then emptied into Lummi Bay rather than Bellingham Bay, as the current channel of the Nooksack River does. At the time, the channel that now serves as the main channel of the Nooksack River was restricted by a massive, mile-long, log jam. This was the result of the timber industry floating logs downriver to ports for processing and shipping.
- Denny Mountain (mindat.org)
Denny Mountain is one of the better known mineral collecting localities in Washington state, containing a wide variety of attractive skarn minerals. It is the site of the original Denny Claims which followed the contact mineralization. Originally located by Artur Denny (one of the founders of Seattle) in 1869, it was the first recorded lode in the Snoqualmie Pass area. Most of the early work there was in search of economic quantities of Iron. The grade found was fairly high in places, but the impurities in the magnetite and hematite made it useless. Some chalcopyrite was also found but the quantity was insignificant for mining.
