Who handles what
For assessment questions about property around Denali Wilderness belong with the borough assessor, since that office keeps the assessment data. Questions about what you can build around Denali National Park and Preserve are for the local planning and health departments, town or borough, depending on location.
Why people still buy them
Buyers and seed dealers around Denali National Park and Preserve rely on them to see ownership across many tracts at once.
A word on accuracy
Closer to Chugach National Forest, listed acreage is an assessed number; only a licensed surveyor can set the real corners on the ground. Out toward Buffalo Soapstone, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Land on the borough line
Matanuska-Susitna Borough touches Anchorage Municipality, Bethel Census Area, Denali Borough, Kenai Peninsula Borough, and Southeast Fairbanks Census Area, all with their own assessor records. Acreage along the edge near Chickaloon can show up in two borough records, so look at the adjacent map too. Out toward Big Lake, our state page lists every neighboring borough map across Alaska.
The paper trail behind a parcel
The map is an index, not the title: recorded deeds, subdivision plats and easements covering ground around Denali National Park and Preserve sit with the State Recorder's Office (Alaska DNR). Around Denali National Park and Preserve, have ready the document number shown in the record panel so staff can find the deed fast.

Using the parcel viewer instead
For current names, use the Alaska Statewide Parcels layer in ArcGIS Map Viewer, across the borough, whether the land is near Chickaloon or elsewhere in the borough.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Denali Wilderness, so load it before you lose signal. A screenshot of the parcel near Buffalo Soapstone with its ID helps when you meet an owner or agent.
