360 Panorama - Pleasant Valley Conservancy
This image was made of 48 individual photos, each at 18-megapixel, resulting in an original image over 800-megapixels! I do have a Quicktime MOV file where this is mapped on a sphere, and you can pan up/down & left/right to interact with it as if you were standing on this road. Email me at jonahwestrich@gmail.com if you'd like me to send it to you (it's about 4MB).

Boundary Waters Canoe Area Wilderness
The lakes of the BWCAW are located in depressions formed by differential erosion of the tilted layers of the Canadian Shield. For the past two million years, massive sheets of ice have repeatedly scoured the landscape; the last glacial period ended with the retreat of the Laurentide Ice Sheet from the Boundary Waters about 17,000 years ago.The resulting depressions in the landscape later filled with water, becoming the lakes of today.
Many varieties of Precambrian bedrock are exposed, including granite, basalt, greenstone, gneiss, as well as metamorphic rocks derived from volcanic and sedimentary rocks. Greenstone of the Superior craton located near Ely, Minnesota is up to 2.7 billion years old, some of the oldest exposed rock in the United States. Igneous rocks of the Duluth Complex comprise the bedrock of the eastern Boundary Waters. Ancient microfossils have been found in the banded iron formations of the Gunflint Chert.

Baxter's Hollow Preserve
"Baxter's Hollow features a scenic gorge cut through Baraboo quartzite by Otter Creek, a fast, clear, nearly undisturbed stream flowing over the large quartzite boulders. Although it supports trout, Otter Creek is better known for its diverse and unique aquatic insect fauna. Cold air drainage has permitted a white pine dominated forest to persist near the stream."

Castle Mound - Black River State Foreset
The Black River State Forest, established in 1957 includes approximately 67,000 acres in Jackson County. The area is unique among the state forests mainly because of its geological features. The Forest lies on the edge of the glaciated central plain east of the rough coulee region or driftless area of Wisconsin. If you hike the nature trail to the top of Castle Mound, one can observe what was once the bed of glacial Lake Wisconsin. Unglaciated buttes, sandstone hills, and castellated bluffs such as Castle Mound dot the vast forest landscape. -Wisc. DNR

Winter Sunset over Blue Mound State Park
For the last 400 million years, most of Wisconsin has remained above sea level, and erosion has carved southwestern Wisconsin into its present much-branched, tree-like drainage pattern of rivers, hills, and valleys. Hundreds of miles of sandstone and limestone have been remove from southern Wisconsin by the streams during the 400 million year erosion cycle.
Southwestern Wisconsin has had nearly all its Niagara dolomite removed. It remains in this region only as tiny remnants atop Blue Mound, Platte Mound, Belmont Mound, and Sinsinawa Mound. If it were not for the hard Niagara dolomite capping, these mounds would have been cut down to the level of the surrounding lowlands. Blue Mound stands hundreds of feet above the surrounding countryside.
Deep down under the Blue Mounds is granite bedrock, the "roots" of mountains that stood here more than 2 billion years ago. The mountains were eroded down to a rolling granite plain.
As Wisconsin warped up and down repeatedly, extensive inland oceans alternately flowed into and retreated from the area. In the process, sand and soft limy sediments were deposited on top of the granite. The first sea covered the area more than 1 billion years ago, and the last (the Silurian Sea) about 400 million years ago.

Rippled Rock River Reflections
"Fifteen thousand years ago during the Wisconsin Glaciation, ice covered the Rock River Basin. The continental glacier sculptured a rolling landscape that supported thickly wooded lands interspersed with oak-savannah prairies, large wetland complexes and numerous large and small lakes. Today, threading through this rich, ecologically diverse landscape is the Rock River and its major tributaries, the Crawfish, Beaver Dam, Oconomowoc, Bark, and Yahara rivers, and Turtle Creek.
The Rock River Basin covers 3,777 square miles and is located in ten counties: most of Dodge, Dane, Rock and Jefferson and parts of Washington, Fond du Lac, Walworth, Columbia, Waukesha and Green Lake counties.
Wisconsin archaeological records indicate that areas of the Rock River Basin were inhabited by the Woodland culture 3000 years ago. These people were 'mound builders' who left their mark on the landscape near waterways by building effigy mounds shaped in the forms of birds and animals. At one time the mounds were prolific, numbering more than 1,500 in Jefferson County alone."

Clear, Superior H2O
"Not only is Lake Superior the largest of the Great Lakes, it also has the largest surface area of any freshwater lake in the world. It contains almost 3,000 cubic miles of water, an amount that could fill all the other Great Lakes plus three additional Lake Eries. With an average depth approaching 500 feet, Superior also is the coldest and deepest (1,332 feet) of the Great Lakes. The lake stretches approximately 350 miles from west to east, and 160 miles north to south, with a shoreline almost 2,800 miles long. The drainage basin, totaling 49,300 square miles, encompasses parts of Michigan, Minnesota, Wisconsin and Ontario. Most of the Superior basin is sparsely populated, and heavily forested, with little agriculture because of a cool climate and poor soils."

Terminal Moraine
The ridge extending to the left from the bluffs on the right was formed from the deposition of sand, rocks, and gravel at the edge of a continental glacier. Known as a 'terminal moraine', it marks the furthest extent of a mile-thick sheet of ice, and formed one of two natural dams which created the current Devils Lake.
