Zone A, AE and X in plain English
Any Crook County parcel shaded as Zone A, AE, AH or AO sits in what FEMA calls a Special Flood Hazard Area, defined by a 1-percent annual chance of being flooded. Zone AE near Hulett means FEMA published a base flood elevation; plain Zone A means no detailed elevation was studied. Land near Hulett in shaded X (Zone B on older maps) falls between the base flood and the 500-year flood. Clear, unshaded X near Sundance is outside the 500-year floodplain.

When the map affects a deal
Here's why the zone matters at a closing in Sundance. If a house near Hulett is mapped in a high-risk zone and carries a federally backed mortgage, flood insurance is mandatory under the Flood Disaster Protection Act, wherever the community joins the NFIP. In Zone X near Sundance, coverage is optional, though a lender in Wyoming can still ask for it. Where a structure near Sundance looks higher than the shading suggests, a Letter of Map Amendment request is the formal route, generally backed by an elevation certificate from a surveyor who works in the county. New construction in a Crook County Special Flood Hazard Area has to meet local floodplain rules, so call the county or the town office in Sundance before work starts.
