World's Highest BASE Jump - Flying from Mt. Everest
Nearly 60 years to the day after the first ascent up Mount Everest, Russian extreme sport star Valery Rozov (48) flew off the north face of Mount Everest - the world's highest BASE jump ever - 7220 meters (23,688ft) above sea level.
The ascent began on the Chinese side on the famous north route. It took him four days to climb from the base camp to the jumping location. At precisely 2:30 p.m. local time he leaped despite adverse weather conditions with temperatures -18 Celsius.
Because the cliff at the top was not very high, the initial moments of the leap in the rarified high altitude air were the most critical phase. Rozov needed more time than usual in the thin air to transition from freefall to flying. After that he flew for nearly a full minute at speeds of about 200 km/h (125 mph) along the north face before he landed safely on the Rongbuk glacier - at an altitude of 5,950 meters

May 18 view from space of Pavlof Volcano
Situated in the Aleutian Arc about 1,000 kilometers southwest of Anchorage, Pavlof Volcano began erupting on May 13, 2013.

The Alaska Volcano Observatory released this update on May 28 at 4 p.m. CDT (21 UTC):
Over the past three days, the eruptive activity at Pavlof have greatly declined. Seismic tremor and small discrete explosions are no longer detected in seismic and pressure sensor data. Satellite observations show no evidence of elevated surface temperatures, volcanic gas or ash emissions. There have been no visual observations from pilots or web cameras of any eruptive activity. Consequently, the Aviation Color Code is being reduced to Yellow and the Volcano Alert Level to Advisory.During past eruptions of Pavlof, the style of eruptive activity fluctuated from higher to lower levels. Therefore, this pause in eruptive activity does not necessarily indicate that the eruption has ended. Renewed activity is possible, and may not be preceded by significant seismic activity. AVO will continue to monitor Pavlof closely.

Members of International Space Station crew (Expedition 36) acquired these images with a Nikon D3S digital camera using 800, 400, and 50 millimeter lenses, respectively. The images are from May 18, 2013, five days after the current eruption began.
