Pewits Nest State Natural Area
"The dominant feature at Pewits Nest is a 30- to 40-foot deep gorge formed during the retreat of the last glacier. Associated with it are Skillet Creek, shaded cliffs, and a northern dry-mesic forest. When Glacial Lake Baraboo drained, Skillet Creek cut a narrow canyon through the Cambrian sandstone, forming a series of potholes and waterfalls. The layers of Cambrian sandstone show that a finer-grained sediment was laid down by the Cambrian seas "inside" the syncline, a process different from that at Parfrey's Glen where coarser Cambrian conglomerates and sandstones are found in layers. Skillet Creek has a gradient of 38 feet/mile and an average flow of 0.8 cfs. Forest cover includes red cedar, white pine, hemlock, and yellow birch." -Wisc. DNR

360-degree Forest Panorama
This one turned out really cool. It's a series of eight or ten HDR shots in the Gotham pine forest. When viewed full-size (about 60 megapixles) this is especially cool, or in an interactive Quicktime VR file. Shoot me a message or email if you want to check this out, and I'll send over the 2MB Quicktime file.

Superior Shore Grass
A lone boulder sits on the edge of this billion year-old basalt cliff - deposited here by glaciers during the last ice-age. Robust grasses grow alone so close to the waters edge, as this particular area lacks soil and nutrients to support larger plants. Any soil which does accumulate is lost to the effects of water and ice during harsh periods of storm and wave action along the shore.

Superior Shoreline
One-billion year old lava flows from the expansion of the Superior basin still reside in their basaltic form along the northern shore of Lake Superior.

Split Rock Lighthouse State Park
"Split Rock Lighthouse State Park is a Minnesota state park on the north shore of Lake Superior. It is best known for the picturesque Split Rock Lighthouse, which was built by the United States Lighthouse Service in 1910. The lighthouse and some adjacent buildings have been restored and the Minnesota Historical Society operates them as a museum. The park also offers scenic hiking, cross-country skiing, and bike trails. There is also a small campground with 22 cart-in tent sites (no vehicle access)." - Wikipedia

Devils Tower National Monument
"Geologists agree that the igneous material intruded and then cooled as phonolite porphyry, a light to dark-gray or greenish-gray igneous trachyte rock with conspicuous crystals of white feldspar. As the lava cooled, hexagonal (and sometimes 4-, 5-, and 7-sided) columns formed. As the rock continued to cool, the vertical columns shrank horizontally in volume and cracks began to occur at 120 degree angles, generally forming compact 6-sided columns. Superficially similar, but with typically 2 feet (0.61 m) diameter columns, Devils Postpile National Monument and Giant's Causeway are columnar basalt." -Wikipedia

Death Canyon: Teton National Park
Following the trail into Death Canyon on a cold and sleeting afternoon. Massive U-shaped valleys such as this one (and most others in the Tetons) were carved by glaciers during past ice-ages.

Grand Canyon of The Yellowstone
"The canyon below the Lower Yellowstone Falls was at one time the site of a geyser basin that was the result of rhyolite lava flows, extensive faulting, and heat beneath the surface (related to the hot spot). No one is sure exactly when the geyser basin was formed in the area, although it was probably present at the time of the last glaciation. The chemical and heat action of the geyser basin caused the rhyolite rock to become hydrothermally altered, making it very soft and brittle and more easily erodible (sometimes likened to baking a potato). Evidence of this thermal activity still exists in the canyon in the form of geysers and hot springs that are still active and visible. The Clear Lake area, which is fed by hot springs, south of the canyon is probably also a remnant of this activity. According to Ken Pierce, U.S. Geological Survey geologist, at the end of the last glacial period, about 14,000 to 18,000 years ago, ice dams formed at the mouth of Yellowstone Lake. When the ice dams melted, a great volume of water was released downstream causing massive flash floods and immediate and catastrophic erosion of the present-day canyon. These flash floods probably happened more than once. The canyon is a classic V-shaped valley, indicative of river-type erosion rather than glaciation. Today the canyon is still being eroded by the Yellowstone River." -Wikipedia

Countryside Rays
Taken enroute to Governor Dodge State Park in the driftless zone of southern Wisconsin. Note the stands of three different tree species along the bottom of this shot.
This sunny Friday was particularly humid due to warm temperatures and excessive snow meltoff, which produced well contrasted rays of light beneath the clouds.

Helena Unit Lower Wisconsin State Riverway
Helena Unit Lower Wisconsin State Riverway viewed from the Shot Tower and Smelter House at Tower Hill State Park.
The Spring Green water tower is visible on the opposite side of the Wisconsin River on the left-hand side of this photo.
The hills visible in the distance mark the edge of the flat, ancient Wisconsin River floodplain which cut through the hills of the Driftless Zone over the span of several ice ages.

Natures Cycle
We noticed this perfectly dead mouse after pausing on an overlook for water and to catch a breath. This is one of several different angles I took of the critter, trying to capture the depth of the bluffs beyond and the brilliant blue sky... I'm sure this guy became quick lunch for a crow, vulture, hawk or land carnivore.

The Baraboo Range
The Baraboo Range consists of highly eroded precambrian metamorphic rock; and is about 25 miles long and varies from 5 to 10 miles in width.
The range is an example of a buried mountain range exposed through erosion, to once again undergo the forces of surface erosion. The rocks are as much as 1.6 billion years old, among the oldest exposed rocks in North America consisting mainly of pink Baraboo quartzite and red rhyolite.
The Wisconsin River, previously travelling in a north to south direction, turns to the east behind it before making its turn to the west towards the Upper Mississippi River. The eastern end of the range was glaciated during the Wisconsinian glaciation, while the western half was not, and consequently, marks the eastern boundary of Wisconsin's Driftless Area.

Positive Contrast
Bright fall foliage nicely contrasts this otherwise muted and foggy afternoon at Devil's Lake. A pilar of Baraboo purple quartzite towers nearly 500 feet above the lake's surface.
