View southeast from Overlook Cabin looking over the Valley of Ten Thousand Smokes. The pyroclastic and ash deposits that fill the valley remain nearly vegetation-free more than 100 years after the 1912 Novarupta-Katmai eruption.

Ascending eruption cloud from Redoubt Volcano as viewed to the west from the Kenai Peninsula. The mushroom-shaped plume rose from avalanches of hot debris (pyroclastic flows) that cascaded down the north flank of the volcano. A smaller, white steam plume rises from the summit crater.

For a behavioral study of Crossarchus obscurus, the long-nosed cusimanse, in Tiwai Island Wildlife Sanctuary, Sierra Leone, West Africa, fishing nets were the most successful method of capturing an entire group of these mongooses, compared to baited live-traps and thatch fences (which channeled animals into live traps, and which were moderately successful).

Cliff Palace, Mesa Verde National Park, Colorado - 1989
Cliff Palace, Mesa Verde National Park, Colorado - 1989The kivas, which were unexcavated by Nordenskiöld, are now exposed. Fewkes did considerable repair of the tower, kivas, and other structures when he excavated the ruin in 1909. Paths for visitors have been added to facilitate access. (Bill Howard).

Geologist, sedimentation expert and Mars Science Laboratory team member David Rubin of the USGS Pacific Coastal and Marine Science Center investigates longitudinal dunes in China's Qaidam Basin. He comments: "The landscape has some similarity with Mars: almost total lack of vegetation and wind-formed landscape."
