Excerpt from Preliminary Report on the Economic Geology of Hazelton District, British ColumbiaThe main valleys have all been eroded in rocks which are very much softer than those which form the hills, further, the cores of the hills are of igneous rocks in small stocks and these have metamorphosed and hardened the surrounding rocks, thus forming hard, resistant areas in a generally soft country. The rivers worked their wa around these areas, choosing the paths of least resistance, ultimately erning the broad valleys and leaving the isolated hills.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
