Isle Royale National Park Vegetation Change Analysis 1996 to 2017 - Randomly Selected Sites Vegetation change is an important issue facing managers at Isle Royale National Park (ISRO). These data were created using high-resolution imagery collected in the winter of 2017 which was compared to the vegetation map of the National Park published in 2000 (project imagery collected in 1994 and 1996). These data review where vegetation cover type, density, and pattern have changed since imagery collection for the 2000 publication and provide a proposed reason for the change.

Isle Royale National Park, Keweenaw County, Michigan. 1971. Isle Royale National Park, Michigan. Characteristic textures of volcanic rocks On Isle Royale: pegmatite from the differentiated zone of the Greenstone Flow on the east end of Passage Island. This rock has a texture in which all of the minerals, especially the plagioclase, are larger when compared with those in most of the other rock types; the elongate plagioclase laths give the rock a matted appearance. Circa 1971. Figure 4-E, U.S. Geological Survey Professional paper 754-C; Figure 12-E, U.S. Geological Survey Bulletin 1309.

Characteristic textures of volcanic rocks on Isle Royale: fine-grained porphyrite from the Scoville Point Flow on the south side of North Government Island. This variety has small, blocky millimeter-sized plagioclase crystals rather uniformly distributed through the groundmass. Circa 1971.
