As mines expanded and North Park's population swelled, the need for timber increased to shore up the mines and build homes for settlers. The abundant forests surrounding North Park provided a ready supply, and logging camps sprang up as enterprising people worked to fill the demand. These isolated camps had to be self-sufficient. Ten to twenty families and dozens of single men lived in rough log-plank cabins and other wooden structures. A store, cook house, and school offered meager amenities. Life was difficult, and the work was demanding and continuous. The primary entertainment was playing cards and school programs. In the forest southeast of the Refuge, Bockman's Timber Camp later served as an internment camp for German prisoners of war during World War Two.
