  • Tanner Springs Park in the Pearl District of downtown Portland, Oregon is a modern-day experiment in sustainable design and stormwater management.  The water feature, designed by Herbert Dreiseitl is an effort to re-create the pre-industrial wetlands and riparian ecology of the original Tanner Creek that flowed to the nearby Willamette River in the early 1800s.  One sustainability feature of the park is the collection, treatment and recirculation of all rainwater that falls within the park.  Additional sustainability features include the re-use of basalt cobbles, or Belgian Blocks, for walkways and the re-use of rusty railroad rails for the undulating wall.

  • "Ancient basalt boulder, fiery heat its moulder, carved and formed by frost and storm..." - the first words of the peom The Cold, Winter Wind by Lorna Peirson. These were the words that inspired this image of a basalt boulder resting on smooth sandstone bedrock in Tooth Gully, Drakensberg.  Tooth Gully lies at the left-hand end of the Amphitheatre, the iconic view of the jagged escarpment wall as viewed from the former Royal Natal National Park. Ukhahlamba-Drakensberg Park, KwaZulu-Natal, South Africa.   Nikon F90; 28-70/3.5-4.5. Fuji RDP-II.

  • Snow on Basalt Crater Wall, Mount Tabor Park. In 1903, John Charles Olmsted of the Massachusetts-based landscape design firm Olmsted Brothers recommended that a city park be developed at Mount Tabor.  Portland Parks Superintendent Emanuel T. Mische, who had worked at Olmsted Brothers, consulted with Olmsted on the park layout and integration of the reservoirs into the park design.  Photo 12/24/2008.

  • Skinner Butte Columns is a small, well-established rock climbing area in a downtown city park in Eugene, Oregon, USA. The rock is columnar basalt formed in a slow-cooling magma intrusion, resulting in relatively uniform polygons and rock of high density and excellent quality.  The cliff was mined in the early 1900s, but the more fractured, unstable face resulting from mining operations has been blanketed with chainlink fence to prevent climbing on the unstable rock.

  • Mount St Helens ash eruption, 2005, viewed from Portland, Oregon.  As if to signal the 25th anniversary of the devastating 1980 eruption, Mount St. Helens released this symbolic outpouring of ash and steam at 17:30 on Tuesday evening, March 8, 2005.  Volcanic ash rose to 36,000 feet and fell as far away as 125 miles east of the mountain. The eruption began with practically no warning, an hour after a magnitude 2.0 earthquake on the volcano's east side, and lasted 30 minutes.  Mount St. Helens, a 8,364-foot (2550m) volcano, is located about 40 miles (60km) northeast of Vancouver, Washington, Portland's sister city across the Columbia River which divides the states of Oregon and Washington.  The river in the photograph is the Willamette River, which divides Portland's east and west sides.  The Columbia River is not visible in this image; it runs perpendicular to the Willamette.  Mount St. Helens was named for British diplomat Alleyne Fitzherbert whose title was Baron St. Helens.  The mountain was named by Commander George Vancouver and the officers of H.M.S. Discovery while exploring the northern Pacific coast from 1792 to 1794.  Mount St. Helens erupted violently at 08:32 on Sunday, May 18, 1980.  Nikon F4S, 70-300/4-5.6D. Fuji RVP100F..

Younger than the hundreds of volcanoes which poured out their lavas in the foot hills of Mt Hood, this cinder cone has withstood the ravages of time to become a part of Mt Tabor.  It now stands peacefully in the City of Roses, the only major city in the United States that has a volcano within its borders.  This tablet was installed by the Geological Society of the Oregon Country, August 8, 1952”.
