Tracking down a Rio Grande County plat book
Out toward South Fork, plat books are commercial atlases, with owner names on each tract, page by page across the county.
Getting to the right map
Your first stop is the Colorado Public Parcel Map; it maps every assessed parcel around Rio Grande National Forest and Monte Vista National Wildlife Refuge. For a home near Monte Vista National Wildlife Refuge, type a street address, an owner's name or a parcel number, then pick the result to center the map on it. Out toward Monte Vista, the record panel usually lists the owner of record, assessed acreage, the parcel number and sometimes recent sales.
Who handles what
For assessment questions about property around Monte Vista belong with the County Assessor, the office behind the parcel record. Questions about what you can build around Alpine are for the local planning and health departments, depending on whether the land is inside town limits.
Legal descriptions in Colorado
Colorado uses the Public Land Survey System, so deeds around Del Norte reference sections and townships. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Rio Grande National Forest can be irregular. Write down the legal description for the tract near Rio Grande National Forest for any title or survey request.
Limits of the parcel data
For a home near South Fork, acreage on the record is an estimate; only a licensed surveyor establishes the real boundary on the ground. Closer to Rio Grande National Forest, records update in batches, so a deed recorded last month can take weeks to appear.
Using it on a phone
The parcel map usually runs in a mobile browser, useful out on a road near Alpine, so load it before you lose signal. A printout of the tract near Rio Grande National Forest keeps working without signal.

When a parcel crosses a boundary
