Travel Gravity Filter for a Large Tract Walk
A day of walking corners is a day of drinking water.

Why this comes up
A day of walking corners is a day of drinking water. Carry water from home. A pocket filter is a backup, not a creek plan.
What to check on the map first
County GIS lines are assessment maps. They are not a survey, and a product will not redraw them.
Open Platbookmapper and choose the state. The directory sends you to the county viewer. Match the parcel ID before you trust a pin on an aerial photo.
A tool that matches the job
Shop the Portable water filter when that is the job in front of you. Carry water from home. A pocket filter is a backup, not a creek plan.
The limit
Filter water you hauled from a known tap, or water a lab has already tested. A steel crock does not make creek water safe.
Walk the parcel in daylight before you trust a gadget at dusk.
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.
