If a legal description for land in Spearfish cites a lot number, you'll need the Spearfish plat map to make sense of it. What this Spearfish guide covers: where plats are filed, plat versus tax map, and what to look for on the sheet.
Who keeps the Spearfish plat map
For land around Deadwood, the deed or parcel record often names the subdivision and plat reference; use it to request a copy.
Opening the official parcel viewer
Your first stop is the Lawrence County Beacon site; it maps every tax parcel around Whitewood and Central City. If you're looking near Whitewood, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. For acreage around Lead, the record panel typically gives the owner of record, assessed acreage, a parcel ID and often a sale date.
Field tips
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Whitewood, but coverage can be spotty out of town. A screenshot of the parcel near Central City with its ID helps when you meet an owner or agent.
Which office to call
If the acreage or value on a parcel near Whitewood looks off go to the Director of Equalization, which maintains the tax roll. Building or septic questions for a lot near Lead need the planning or permitting office, and the answer depends on jurisdiction.
How land is described here
South Dakota uses the Public Land Survey System, so rural legal descriptions near Deadwood cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though real sections near Lead vary in size. Copy the legal description from the record for the parcel near Lead for any title or survey request.
City limits and county records
Spearfish lies within Lawrence County, South Dakota, which means parcel data comes from the county. In and around Central City, City or town hall handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Acreage past the town limits toward Central City often answers to county rules rather than the town's.
The paper trail behind a parcel
The map is an index, not the title: recorded deeds, plats and easements for land near Deadwood are kept by the Register of Deeds. Around Lead, have ready the instrument number listed on the parcel record so staff can find the deed fast.
Recorded plat or GIS layer
The Lawrence County Beacon site draws parcels for taxes, whereas the plat carries surveyed dimensions.
Reading the plat sheet
For a home near Central City, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
What the map can't tell you
Listed acreage is an estimate; only a licensed surveyor sets the real corners on land around Deadwood. For land near Deadwood, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Online indexes and office visits
For a parcel near Deadwood, some counties put plat images online, while others require a visit or a request; copy fees are usually small.
Lawrence County in a few facts

Roughly 28,053 people call Lawrence County home (Census estimate, 2023) spread over roughly 800 square miles. Features like Black Hills National Forest are easy to spot when you zoom out from Whitewood.
When a plat changes

Neighboring parcel maps
Lawrence County borders Butte County, Meade County, Pennington County, Crook County, WY, and Weston County, WY, all with their own assessor records. Acreage along the edge near Lead may be split across two assessors' files, so look at the adjacent map before you assume the acreage. For a parcel near Central City, the Platbookmapper state page lists every bordering county map for South Dakota.
Land outside a subdivision
Rural land near Whitewood that was never subdivided may have no plat at all; look for a recorded survey for land near Central City.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
