A word on accuracy
With a lot near Methow, the acreage figure is a tax-roll number; just a licensed surveyor sets the real lines on the ground. If you're looking near Loomis, records update in batches, so a deed recorded last month may not show yet.
How land is described here
Washington uses the Public Land Survey System, so deeds around Omak reference sections and townships. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though corrections make some sections near Okanogan–Wenatchee National Forest odd-sized. Keep the legal description for land near Okanogan–Wenatchee National Forest for any title or survey request.
Using the parcel viewer instead

Which office to call

The paper trail behind a parcel
For land near Loomis, the map is an index, not the title: recorded deeds, subdivision plats and easements for parcels in the county are kept by the County Auditor. Long-held tracts around Conconully can trace back through several deeds, so a title company is worth hiring before a purchase.
On site with the map
Most viewers work in a phone browser, useful out on a road near Methow, so load it before you lose signal. A saved image of the lot near Okanogan–Wenatchee National Forest and its lines is a good backup.
Plat book vs. recorded plat
