2. Salton Sea The Salton Sea is an inland saline lake, part of the larger Colorado Desert in Southern California, USA.

3. The Salton Sea It was created by accident in 1905 when increased flooding on the Colorado River allowed water to crash through canal barriers and for the next 18 months the entire flow of the Colorado River rushed downhill into the Salton Trough. By the time engineers were finally able to stop the breaching water in 1907, the Salton Sea had been born- 45 miles long and 20 miles wide-equaling 110 miles of shoreline.

5. Chisholm Trail The “Chisholm trail” was a dirt trail used in the latter 19 th century to drive cattle overland from ranches in Texas to Kansas railheads. The trail stretched from southern Texas across the Red River, and on to the railhead of the Kansas Pacific Railway in Abilene, Kansas, where the cattle would be sold and shipped eastward.

6. Chisholm Trail The trail is named for Jesse Chisholm who had built several trading posts in what is now western Oklahoma before the American Civil War. He died in 1868, too soon to ever drive cattle on the trail.
