Mid- to Late-Neoproterozoic (ca. 680 - 665 Ma) sedimentary rocks of northern Utah and southern Idaho provide a record of the Earth system during and immediately following “Snowball Earth” glaciations.

Strata in this structurally complex region are not clearly correlated. Although a geochronologic framework is currently emerging, the stratigraphic context of these units is not clear.

What was the nature of the biosphere during this time? What was the state of primary productivity? What did these paleoecosystems look like?

Are there syn-glacial carbonates preserved in this region? What can they tell us about global climate or depositional environment?

How do regional datasets fit into the global picture?
