Seifert surfaces are orientable surfaces whose boundary forms a knot or link. This is a Seifert surface of the trefoil knot. See my website if you want instructions on making these!
Hello from New Orleans, Louisiana
I am demoing Windows Home Server and Windows 7 at the Worldwide Partner Conference '09 at the Morial Convention Center in the OEM area of the expo hall if you're at the conference and want to stop by and say hello!
Mudroom locker features Corian® Solid Surface as the back in Cameo White and Corian® Quartz Portoro as the seat.
I will be participating in the Surface exhibit opening tonight at Abernathy Arts Center in Sandy Springs. As part of the opening, Evereman and I will be offering some artwork for you to take home, if you can find it. I have five kittens for you all. Four are wooden, one is magnet. More info on the event is here: www.facebook.com/event.php?eid=268361236517174
Hot springs are sites where groundwater emerges at the surface and the water is hotter than the human body. In many cases, hot spring water is boiling hot, or close to it. At Yellowstone in Wyoming, most hot spring water precipitates opal (hydrous silica, SiO2·nH2O), resulting in buildups of geyserite, a chemical sedimentary rock. Some Yellowstone hot springs precipitate calcium carbonate (CaCO3). Seen here is a hot spring in Hot Springs National Park in Arkansas. The algae-covered rocky buildup is calcium carbonate. Chemical sedimentary rocks of calcareous composition formed by hot spring water include "calcareous tufa" and "travertine". I'm not entirely convinced there is a difference - the terms are often used interchangeably. My understanding is that "calcareous tufa" (a horrible term, by the way) is a porous, friable precursor to travertine. Travertine also forms in caves (calcareous speleothem) and at some cold springs.
Supposedly, the original tufa/travertine deposits here have long since been destroyed and the layout of hot springs and the drainage patterns are all artificial. The modification took place to accommodate the need to pipe hot water to nearby bathhouses in early days. Tufa/travertine deposits now at the site are probably all secondary.

From park signage:
Thermal Cascade was designed to recreate the natural scene of hot spring water cascading down tufa cliffs. In cool weather the vapor is reminiscent of the clouds that once billowed from open springs along the lower slope.

Tufa Terraces
Before the bathhouse era, this lower side of the mountain was covered with massive terraces of tufa (travertine). Tufa is mostly calcium carbonate, which precipitates out as the spring water cools. In 1834 a British geologist observed that “The travertine . . . sometimes presents abrupt vertical faces of from 15 to 25 feet high.” Tufa formations are still visible along this trail.
After a short ascent past tufa outcroppings and the Thermal Cascade, Tufa Terrace Trail crosses the Grand Promenade. From there you can reach the Peak Trail and continue up Hot Springs Mountain.

THIS VALLEY, LONG KNOWN BY THE INDIANS AS “TAH-NE-CO,” “THE PLACE OF THE HOT WATERS,” AND ACCORDING TO TRADITION REGARDED BY THE DIFFERENT TRIBES AS NEUTRAL GROUND, WAS FIRST VISITED BY WHITE MEN ON SEPTEMBER 16, 1541, WHEN HERNANDO DE SOTO AND HIS MEN CAMPED IN THIS VICINITY AND WERE LED HERE BY THE INDIANS. ACCORDING TO RECORDS OF RODERIGO RONJEL, SECRETARY TO DE SOTO, AND THE “GENTLEMAN OF ELVAS,” WHO WAS ALSO A MEMBER OF THE COMPANY, THEY BATHED IN THE HOT WATERS AND DEPARTED OCTOBER 5, 1541.
THIS MARKER IS PLACED HERE BY THE HOT SPRINGS, ARKANSAS, CHAPTER OF THE DAUGHTERS OF THE AMERICAN REVOLUTION

Detail from a jacket woven by Dee J. Surface design and knitted sleeve detail, make this jacket very special.
I went to Carrizo Plain to shoot wildflowers. Unfortunately, no spectacular displays of color. This was the best spot we found. I shot film! Canon Ftb 85mm f1.2.
