See trail improvements including new bridges, removal of invasive vines from trees, benches for viewing the river, and other work that has recently be done to make your trail experience more pleasant and fun.

Gulf oil

John M. Greer discusses magical thinking and the BP spew. He answers a question that I, former repair plumber, have been asking. The pressure of the oil/gas, 13,000psi. One other pressure question, water pressure at 5,000 feet?

Meanwhile, pressure in the well continued to rise Monday, albeit slowly, reaching 6,811 pounds per square inch, Allen said in the late afternoon. He said the pressure was rising about one pound per hour.

This, too, has triggered debate among BP and U.S. officials, who had expected the pressure to hit 8,000 psi and who thought that lower pressure readings would be a sign that oil and gas was leaking into rock formations through damaged well equipment. But because of the steady increases in pressure, BP and government scientists are wondering whether so much oil and gas had been spilled already that the pressure in the partly depleted reservoir has been reduced.–WaPo 7/20/10
