Missoula Flood Rhythmites

Lake Missoula filled many times and emptied catastrophically in many Missoula Floods. Rhythmite sequences [a series ofrepeated beds of similar origin] at numerous localities provide this evidence: slack-water rhythmites in backfloodedtributary valleys below the dam indicate multiple floods, and varved … [Read More Here…]

Ice Age Flood Simulation Video

An interesting, 4 minute captioned video from UC Santa Cruz (ingomar200) of a satellite-view computer simulation illustrating flood paths and transient lakes of an Ice Age Flood. The video shows a physics-based computer simulation of the Great Flood from Glacial Lake Missoula … [Read More Here…]

Ice Age Floods Touchet Bed Rhythmites

The Touchet Beds at Burlingame Canyon, White Bluffs, and Granger, WA are stacked lake deposits (rhythmites) from temporary lakes that formed as Ice Age Flood waters backed up behind the hydraulic dam constriction at the narrow Wallula Gap. Sediment thicknesses and … [Read More Here…]

Williams Lake Cataract Video

Williams Lake Cataract is an ancient, dry waterfall left behind along the Cheney-Palouse Scabland Tract in eastern Washington after Ice Age flooding recessionally ripped out underlying basalt to produce this massive cataract. Video produced by Bruce Bjornstad, Ice Age Floodscapes … [Read More Here…]

The Great Blade – Bruce Bjornstad Video

…there were a few double falls each member of which receded at approximately the same rate, so that the island in mid-channel became very much elongated, like a great blade, as the falls receded and the canyons lengthened.” J Harlen … [Read More Here…]

Ice Age Floods – Giant Current Ripples

Check out this 2-Minute Geology expedition with Nick Zentner and Tom Foster exploring the Giant Current Ripples at West Bar and Camas Prairie. Ice age floodwater 650 feet deep – moving at 65 miles per hour – left Giant Current … [Read More Here…]

Ice Age Floods’ Features

This is an amazing compilation of extra ordinary photographs that have been expertly labeled to assist the viewer’s understanding of the evidence supporting the creation of the Channelled Scablands in Eastern Washington State, USA.  The photographs are panned and zoomed … [Read More Here…]

Giant Current Ripples at West Bar

Massive current ripples and dunes cover the surface of the West Bar pointbar. These unusual, huge current ripples deposited by Ice Age floods in eastern Washington are probably the largest and best example of giant current ripples on Earth. Video … [Read More Here…]

Glacial Lake Missoula – A Portrait

In this video Tom Davis flies you back some 13,000 years ago to see and hear what the landscape of Glacial Lake Missoula might have looked and sounded like. A virtual recreation of the magical ice-age lake and its catastrophic … [Read More Here…]

Lava + Ice + Water = Floods Geology

Floods of lava (Columbia River Basalts) and Ice Age Floods of water (Lake Missoula floods and the Bonneville Flood) are world-famous topics among geologists. To have both sets of floods in the same area means the geology of the Inland … [Read More Here…]

Devils Canyon Coulee

An unsuspecting coulee in the southern Channeled Scabland, Devil’s Canyon cuts a straight, south-southeast trending, 600-foot deep gash through the Palouse wheat lands from Kahlotus at the lip of the Washtucna Coulee to the Snake River at Lower Monument Dam. … [Read More Here…]

Nova – Mystery of the Mega Food

Monument Valley, the Grand Canyon, Niagara Falls: these ancient wonders show how nature’s forces have shaped the face of our planet on a vast timescale, how great landmarks are the work of millions of years of slow, imperceptible erosion by … [Read More Here…]

Palagonite Maar Near Hood River

Just west of Hood River is a distinctive, short (<500 m) section of stratified orangeish oxidized volcanic tephra and highly fractured lava bombs.  This mixture of oxidized volcanic particles ranging down to sub-micrometer sizes mixed with the larger lava bombs is a palagonite tuff.  This deposit is … [Read More Here…]

Ortley Thrust in the Columbia Gorge

The near vertical beds known locally as The Pinnacles lie on the Washington side of the Columbia River Gorge, just west of Doug’s Beach and across the Columbia from Rowena OR, and are readily visible from I-84.  The WA Interactive … [Read More Here…]
