 Iowa is beautiful in the spring, but the weather in 1846 ran from scorching heat to rain and mud. Their travel conditions are interesting. On the one hand we have the lush prairie, on the other hand it's rainy season. There are some interesting descriptions of traveling across Iowa during this season. Newell Knight loved the rich and variegated prairie with its grasses and flowers and fragrances. Ursula Haskell said, we traveled for hours.
