2017 ASA Regionals, Redfield, SD - Day 2

The team had a productive day of practice, describing 4 pits (2 as individuals, 2 as a team) in and around the towns of Redfield and Doland. Our day started with a Haplustoll formed in Alluvium on a stream terrace of the James River.

We then ventured into the Lake Dakota lacustrine plain to describe a Natrustoll formed in lacustrine sediments:

  2. I'm very jealous of the different soil formation factors. Have fun and let your mind be a sponge!

  3. Lots of carbs
    Look for gypsum
    Columnar found
    Natric is in vision
    Lake plain clay
    Good for molding
    Keep It away from Goldy
