Dry Falls is a 3.5 mile long scalloped precipice in central Washington, on the opposite side of the Upper Grand Coulee from the Columbia River, and at the head of the Lower Grand Coulee. Ten times the size of Niagara, Dry Falls is thought to be the greatest known waterfall that ever existed. According to the current geological model, catastrophic flooding channeled water at 65 miles per hour through the Upper Grand Coulee and over this 400-foot (120 m) rock face at the end of the last ice age. At this time, it is estimated that the flow of the falls was ten times the current flow of all the rivers in the world combined.

Nearly twenty thousand years ago, as glaciers moved south, an ice sheet dammed the Clark Fork River near Sandpoint, Idaho. Consequently, a significant portion of western Montana flooded, forming the gigantic Lake Missoula. About the same time, Glacial Lake Columbia was formed on the ice-dammed Columbia River behind the Okanogan lobe of the Cordilleran Ice Sheet. Lake Columbia's overflow – the diverted Columbia River – drained first through Moses Coulee and as the ice dam grew, later through the Grand Coulee.

Eventually, water in lake Missoula rose high enough to float the ice dam until it gave way, and a portion of this cataclysmic flood spilled into Glacial Lake Columbia, and then down the Grand Coulee. It is generally accepted that this process of ice-damming of the Clark Fork, refilling of Lake Missoula and subsequent cataclysmic flooding happened dozens of times over the years of the last Ice Age.[1][2]

This sudden flood put parts of Idaho, Washington, and Oregon under hundreds of feet of water in just a few days. These extraordinary floods greatly enlarged the Grand Coulee and Dry Falls in a short period. The large plunge pools at the base of Dry Falls were created by these floods.

Once the ice sheet that obstructed the Columbia melted, the river returned to its normal course, leaving the Grand Coulee and the falls dry. Today, this massive cliff can be viewed from the Dry Falls Interpretive Center, part of Sun Lakes State Park, and located on Route 17 near the town of Coulee City. Admission is free however a Discover Pass is required for parking; 5$ a day or 30$ for the year.

Tytul polski: " Wodospad... wysuszony... "

Wodospad Suchy (ang. Dry Falls) – urwisko w kształcie półkola (dawny wodospad w czasie ostatniej epoki lodowcowej), znajdujące się w górnej części starego koryta Grand Coulee rzeki Kolumbii, w środkowej części stanu Washington w USA.
Wygląd

Wodospad Suchy jest uważany za największy kiedykolwiek istniejący na ziemi wodospad. Geolodzy spekulują, że podczas katastrofalnych powodzi w czasie ostatniej epoki lodowcowej, przepływająca przez górną kaskadę woda osiągała prędkość ponad 100 km/h przy ok. 90 m wysokości. Szacuje się, że przepływ wodospadu był dziesięć razy większy niż suma wszystkich obecnie płynących rzek na świecie.

Wodospad ten był 10 razy większy od wodospadu Niagara. Jego łączna długość miała wynosić 5,63 km, a wysokość urwiska dochodzić do 121 m.

Witaj Tomeczku :)

Bardzo ciekawe miejsce z niesamowita historia.
Jak sie patrzy na te "kaluze", to az nie chce sie wierzyc, ze kiedys byl to najwiekszy wodospad na swiecie.
Krzak na pierwszym planie jest dodatkowa atrakcja, wyglada jak kwitnaca bawelna.

Kompozycja bardzo efektowna z ciekawymi szczegolami w naturalnych kolorach i ladnym swietle.
Piekny strzal, bardzo mi się podoba!

Usciski...Barbara

This is just beautiful, Tomasz!
Great details and well captured light with superb contrasts within the shot from a high POV.
The colors are natural and exposure is well handled.
Good work!

Have a nice weekend.

Best regards,

Hi Tomasz,
A lovely landscape shot of these rather dry Falls. I like the pattern of the water way with such nice reflections. An interesting wide angle shot.
Very neat work.
Regards,

Francis Xavier
