What reading level is Wisconsin Its Geology And Physical Geography a Popular Account of the Natural book?
To quickly assess the difficulty of the text, read a short excerpt:
" The Apostle Islands, so called from their number, twenty- four, are, even to the most casual observer, evidently detached portions of the mainland, broken fragments of the once more extensive Bayfield Peninsula. They are essentially flat tables of the red Lake Superior sandstone covered in part by glacial drift and with the edges cut into bluffs by the waves.
The surface of the interior of the adjacent mainland is very ragged, being cut up by preglacial valleys in the hard Archean rocks, but ...the shore is flatter because the softer sandstone has yielded more readily to the erosion of the glaciers, and the pre- glacial valleys are filled with drift. As mentioned above, the Apostle Islands were in preglacial times a portion of the main- land which was cut up by stream valleys into isolated blocks, and as the land sank the deep valleys were filled by the waters of the lake and the blocks became islands. This subsidence is also shown in the condition of the mouths of the rivers, the val- 90 WISCONSIN leys of which are "drowned, " and in the destruction of the pre- viously formed bars.
