Satellite Images for Bear Creek

A series of satellite images has been compiled to help readers learn the geography covered by Bear Creek.

The images are in two sets.

One set shows satellite images upstream from the Molalla STP. This is the headwaters area, from Coleman Ranch west to the western edge of Molalla.

The other set shows satellite images downstream from the Molalla STP. to the convergence with the Pudding River (just south of Aurora) and the north flow into the Molalla and Willamette Rivers just west of Canby.

USGS Topo Map of the Bear Creek Area

This is a color topo map by USGS. The original USGS data was compiled using 1954 aerial photos, and photorevisions (in magenta) were added using 1985 aerial photos.

Although the map data is nearly thirty years old, the topography is still very accurate, as is most of the road system. The 1985 map also reflects substantial development of sawmills during the three decades, from 1954 to 1985. Note the grouping of magenta rectangles south of town, at the Avison mill site; these are all mill buildings and structures, added during the mill’s peak (and pentachlorophenol) years.
