When a deed near Mount Carmel says lot and block, look up the Shamokin plat map it refers to. Covered here for Shamokin: where plats are filed, how a plat differs from a parcel map, and what to look for on the sheet.
The Shamokin plat map: start here
For a subdivision near Mount Carmel, the deed usually cites the plat; bring that to the recorder's office or its online index.
The free map to start with
Your first stop is the Northumberland County Basemap viewer; it maps every assessed parcel in the county, Kulpmont included. If you only know roughly where the land is, follow Interstate 180 on the aerial and click the parcel itself. For acreage around Herndon, the record panel normally shows the owner of record, acreage on the tax roll, a parcel ID and sometimes recent sales.
Getting answers from the right desk
If the acreage or value on a parcel near Northumberland looks off are handled by the county assessment office, the office behind the parcel record. Building or septic questions for a lot near Kulpmont are for the local planning and health departments, town or county, depending on location.
Metes and bounds instead
Acreage around Mount Carmel outside a subdivision may have no plat at all; look for a recorded survey for land near Marion Heights.
Limits of the parcel data
Tax maps are drawn for assessment, not measured on the ground, so a tree line near Sunbury often sits a few yards off the line on screen. For acreage around Mount Carmel, records update in batches, so a deed recorded last month can take weeks to appear.
Shamokin and the county around it
Shamokin sits in Northumberland County, Pennsylvania, which means parcel data comes from the county. For a parcel near Northumberland, city or town hall handles matters such as zoning, permits and utilities inside its limits, while the county keeps the tax map. Land beyond the city limits out by Mount Carmel generally falls under county rules, not municipal ones.
When a parcel crosses a boundary
Northumberland County borders Columbia County, Dauphin County, Juniata County, Lycoming County, and Montour County; every one of them runs a separate parcel map. A tract near the line by Herndon may show up across two assessors' files, so open the neighboring map as well. If you're looking near Northumberland, our state page lists every bordering county map for Pennsylvania.
Amended plats
An amended plat may change lots around Herndon, so check for later filings; vacated streets or alleys also get recorded.
Using it on a phone
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Marion Heights, but coverage can be spotty out of town. A saved image of the lot near Kulpmont and its lines is a good backup.
Places you'll see on the map
Sunbury serves as the county seat, home to the main records offices. Smaller places on the map include Kulpmont, Marion Heights, and Mount Carmel, where town lots give way to larger tracts. Around 90,120 people call Northumberland County home (Census Bureau estimate, 2023) on roughly 458 square miles. Northumberland County dates to 1772, and some chains of title near Marion Heights are long. Landmarks such as Susquehanna River help you orient on the aerial around Sunbury.
Legal descriptions in Pennsylvania
Tracts outside towns near Sunbury commonly use metes-and-bounds descriptions, which trace the boundary call by call. Subdivision lots in Mount Carmel usually use lot and block from a recorded plat instead, which is simpler to follow. Keep the legal description for land near Marion Heights for any title or survey request.
Recorded plat or GIS layer
The Northumberland County Basemap viewer draws parcels for taxes, but the recorded plat is what the deed relies on.
Deeds, plats and who keeps them
Before you sign anything, get the recorded deed from the Recorder of Deeds; the parcel map near Sunbury only summarizes it. Long-held tracts near Sunbury may go back through a long string of deeds, and a title company can sort it out before a purchase.
Reading the plat sheet
Easements on the plat near Sunbury can block a shed or pool; check the plat notes and any covenants.
Requesting the plat
For land near Sunbury, some counties put plat images online, otherwise call or visit with the reference; small fees are common.

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.
