Let's stay in Yellowstone for another week, as it is so delightful here.
Once again I am repeating the publisher information because - well maybe you might be interested in purchasing some postcards or postcards? The graphics are fantastic.
The back of this card says:"Works Progress Administration (WPA) circa 1939, Artist Unknown. Between 1935 and 1943 the WPA's Federal Art Project printed over two million posters in 35,000 different designs to stir the public's imagination for education, theater, health, safety, and travel. Due to their fragile nature only two thousand posters have survived. The National Park image shown here is also available in the original poster format from many National Park bookstores."Published by Ranger Doug Enterprises. (1-888-972-7678) Seattle, WA.
To see the Lower Falls of the Grand Canyon of the Yellowstone from this angle, you'd have to hike down into the valley - I read that it is a strenuous hike. I've only seen the Lower Falls from a convenient highway pullout. The falls are 308 feet tall. See the Park's webpage on the Falls for more information.
