Heading west from Fort Mandan, April 14, 1805 Lewis' Diary

The land after Fort Mandan is beautiful, and we have encountered many new species of wildlife. There is an increasing amount of large animal tracks, the creature is unknown though we assume it is a bear. One burden we have encountered is the sand storms created by the high winds. We are in one place currently trapped by one such storm. Some of the men wish to wait it out, others wish to push on. Clark and I are deciding to stop. Such high winds and bad visibility can lead to more dangers than we need at the beginning of our trip.
