Around Camp Crook, the official source is FEMA's Flood Map Service Center: enter the street address, then open the map view for that panel. A tract near Custer National Forest without an address can still be found: pan from the closest town and click the spot.
Where the parcel data lives
Your first stop is the Harding County CAMAvision map; it covers every assessed parcel from Ralph to Ladner. Around Ludlow, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. If the land is near Ludlow, copy the parcel ID while you have it open; every records desk in the county will want it.
Legal descriptions in South Dakota
South Dakota follows the Public Land Survey System, so deeds around Ladner reference sections and townships. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though corrections make some sections near Karinen odd-sized. Copy the legal description from the record for the parcel near Custer National Forest for any title or survey request.
Questions to ask before you buy
If you're looking near Ralph, ask the listing agent for any Elevation Certificate before closing; an insurance quote early keeps the budget honest.

What the map can't tell you
If you're looking near Ludlow, the acreage figure is a tax-roll number; only a licensed surveyor can set the real boundary on the ground. For property near Ludlow, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Beyond the mapped zones
Creeks and ditches near Buffalo may not have detailed mapping, so walk the land after rain. Marshy spots near Karinen can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
