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.

Cinder cones at the summit of Mauna Kea. Mauna Kea is a dormant shield volcano on the north end of Hawaii Island. Astronomical observatories in the foreground.

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).

Lava flows from a lava tube into the sea near Kupapau Point on Hawai'i Island. From the Kilauea East Rift Zone (ERZ) eruption, November 27, 1989. Episode 48 of the Kupapau Lava Flow.

Lava flows from a lava tube into the sea near Kupapau Point on 11/27/1989. From the Kilauea East Rift Zone (ERZ) eruption, eruption pisode 48, Kupapau lava flow. Hawai'i Island.

A downtown building at the corner of Alice and 13th Streets lost part of its unreinforced facade and brick masonry.

Pahoehoe ropes form in the Wahaula Lava Flow across from Wahaula Visitor Center on Hawai'i Island during the Kilauea East Rift Zone (ERZ) eruption on 6/15/89.

The 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." 

This image was taken above the Santa Catalina Highway near mile 2.8 a few months after a fire burned across a south-facing slope. The saguaros are showing the effects of being scorched but are still standing. (Raymond M. Turner).

Bystanders watch steam rising from Queens Bath as lava flow enters the water. Lava overran Highway 130 at 0748 Hawaii Standard Time on the same morning at the western margin of the Kapa'ahu flow. By the end of the day, Punalu'u heiau was overrun, and Queens Bath was filled with lava.

A timelapse on the Great Salt Lake Hydro Mapper site shows changes in the surface area of the lake from 1985-2021. These stills show a comparison of the lake between 1986 and 2021.
