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 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.

Golden Sundog
22° halos form when the sky contains millions of poorly oriented ice crystals. Some of these happen to be aligned perpendicular to the sun light as viewed by one observer which produces the illuminated 22° circle, while other crystals produces the same phenomenon for other observers.
Like other ice halos, 22° halos appear when the sky is covered by thin cirrus clouds containing the ice crystals which causes the phenomenon. Small colourful coronas much nearer the sun produced by water droplets can occasionally be confused with 22° halos. -Wikipedia

Natural Bridge State Park
Natural Bridge and Rockshelter contains the largest natural bridge known in Wisconsin, created by wind erosion and weathering of the sandstone. The arch measures 25 feet in width and 15 feet in height on its inside dimensions. The top is 35 feet above ground level. At the base of the sandstone bridge is a rockshelter 60 feet wide and 30 feet deep. A partial excavation at the site revealed Woodfordian and Archaic inhabitant artifacts with earliest estimates of human occupation between 9000 and 8000 B.C. Animal remains identified include 15 mollusk species and 50 vertebrate species. Of special interest are the remains of passenger pigeon, turkey, elk, wolf, bobcat, fisher, marten, and mountain lion. The surrounding uplands are wooded with oak and other hardwoods. Small prairie remnants with Indian grass, little blue-stem, grama grasses, and cactus occur on the ridge tops. The shaded cliff community contains many unusual plant species including walking fern, slender lip fern, and two rare species - cliff goldenrod (Solidago sciaphila), and purple cliffbrake (Pellaea atropurpurea). Natural Bridge and Rockshelter is owned by the DNR and was designated a State Natural Area in 1973.

Purple Quartzite
The quartz grains that formed the original sandstone appear to have come largely from erosion of the Penokean Mountains to the north. These mountains formed about 1.85 billion years ago in the Early Proterozoic Eon, and the sandstone seems to have been laid down in the subsequent 200 million years. This was then subducted into the earth where pressure and heat transformed before after millions of years it rose to the surface as the colorful quartzite we see today.

Rocky Arbor State Park
Rocky Arbor State Park is a 231 acre Wisconsin state park in the Wisconsin Dells region. The park was established in 1932 to protect sandstone outcrops eroded into picturesque walls and ledges.
The region is formed from Late Cambrian sandstone deposited 500 million years ago at the bottom of shallow inland seas. Much later the Wisconsin River flowed over this tract of land, carving channels into the sandstone. The river has since changed course, now running 1.5 miles to the east, leaving the rock walls of its former gorge exposed. A small creek now flows through the park, though in the opposite direction as the river once did.

Above the World
Looking east from the West Bluff of Devils Lake miniaturizes beach-goers and the park pavilion. Climbing several hundred quartzite steps and hiking hundreds of feet of steep path lead to this outlook, which surprisingly is one of the lowest lookouts on this trek.
The other photos of Devils Lake were shot from the beach, below, and from the adjacent side of the lake, the East Bluff Trail.

Indian Lake State Park
Indian Lake Park lies at the edge of the un-glaciated or 'drift-less' area of southwestern Wisconsin. Here, features of both glaciated and un-glaciated land are prominent. The steep slopes of exposed rock indicate that this valley was never completely covered with ice. Yet the large boulders found in the draws and on the valley floor could only have been brought here by a finger of ice, which fanned out from the main body of the glacier.
Indian Lake is one of many shallow kettle lakes in this area, created when the glacier retreated. The out-wash plain by the lake was formed when glacial melt-water carried large quantities of silt and sand into the valley.
Plant life at Indian Lake is very diverse. The cool north-facing slope along the lake is dominated by paper birch, while on the hilltops ancient gnarled oaks are being crowded by younger hardwoods. An abundance of brambles and aspens indicate logging and grazing once took place in the woods.
For several hundred years Indians camped at the southwest end of the lake. During that period, the slopes on the hills above were quite open and covered with prairie grasses and wildflowers. Frequent fast-moving prairie fires helped keep these areas free of trees. When settlers stopped the fires, trees began to fill in the open spaces. Today only a few small patches of prairie remain on the very dry southwest-facing slopes.
