Crooked Falls

At about ten o’clock on the morning of June 14, 1805, Captain Lewis took his gun and his espontoon and set out on a short walk up the north side of the river (at right in this photo), to see how far the rapids extended above the “grand Fall.” With the Hidatsas’ assurance of a half-day portage still in mind, he fully expected he would be back at camp by noon.

After passing one continued rapid and three small cascades of about four or five feet each[,] at the distance of about five miles I arrived at a fall of about 19 feet; the river is here about 400 yds wide. this pitch which I called the crooked falls occupys about three fourths of the width of the river, commencing on the south side, extends obliquly upwards about 150 yds.[,] then forming an accute angle extends downwards nearly to the commencement of four small Islands lying near the N. shore; among these Islands and between them and the lower extremity of the perpendicular pitch being a distance of 100 yards or upwards, the water glides down the side of a sloping rock with a volocity almost equal to that of it’s perpendicular decent.
For a time, later in the nineteenth century, it seemed to some viewers that “horseshoe fall,” would be more descriptive, but Lewis’s name has prevailed. The islands and sloping rock Lewis noted have been obliterated by the in-fill on the north bank, which covers three large pipes that carry water from an intake above Rainbow Fall to a powerhouse a short distance below Crooked Falls.

Of all the falls of the Missouri, this one remains the nearest to the way it looked to Lewis and Clark.

Just above these falls, the captain continued, “the river makes a suddon bend to the right or Northwardly. I should have returned from hence but hearing a tremendious roaring above me I continued my rout across the point of a hill a fiew hundred yards further.” — lewisandclark.org

Great Falls Storm

There were some ominous looking clouds to the south on the hike down to Crooked Falls. This would have been the area where Lewis and Clark made their portage around the falls.

Montana

This photo was taken along Highway 287 just north of Three Forks, MT. The highway follows the Missouri. This scene is just to the west and would be what Lewis and Clark saw as they made their way to the three forks.

Grand Prismatic Spring

The Grand Prismatic Spring in Yellowstone National Park is the largest hot spring in the United States, and the third largest in the world,[3] after Frying Pan Lake in New Zealand and Boiling Lake in Dominica. It is located in the Midway Geyser Basin.

Grand Prismatic Spring was noted by geologists working in the Hayden Geological Survey of 1871, and named by them for its striking coloration. Its colors match the rainbow dispersion of white light by an optical prism: red, orange, yellow, green, and blue.[4] — From Wikipedia.

Excelsior Geyser Crater

From Wikipedia: The Excelsior Geyser pool discharges 4,000 to 4,500 gallons (15,100–17,000 l)[5] of 199 °F (93 °C)[3] water per minute directly into the Firehole River. In the late 19th century (there was possibly some activity in 1901 too), it was an active geyser that erupted frequently. Most eruptions were about 100 feet high, although some exceeded 300 feet (91 m) in both height and width. It is believed that the powerful eruptions damaged its internal plumbing system, and it now boils as a productive hot spring most of the time.
