How we measure
  • Average: every USGS 3DEP bare-earth cell of land inside the Census county boundary (TIGER/Line, Jan 1 2026), weighted equally, on a 2 arc-second (≈200 ft, 62 m) grid, coarsened from 1 arc-second so the whole area fits one run. Land means the boundary minus Census area water (on this grid, water areas of at least half a cell).
  • Highest and lowest: the highest land cell, re-read at 1 arc-second around the 25 highest grid cells. Lowest: the lowest land cell, re-read at 1 arc-second around the 25 lowest grid cells; coastal ground within 3 ft (1 m) of named tidal water counts as sea level.
  • Pits: the lowest point is the lowest ground outside closed hollows (quarry floors, mine pits, terrain-model artifacts): any hollow under 0.4 sq mi (1 km²), and any hollow under 2 sq mi (5 km²) whose floor is more than 100 ft (30 m) below its rim; and outside patches below sea level of under 0.4 sq mi (1 km²). The single lowest 3DEP cell, 280 ft at 28.0460° N, 98.9215° W, is in such a hollow or patch and is not counted.
  • Nearby Places: neighboring counties and rankings use each one's average elevation, on its own grid, the same figure its page shows. Peaks and hills: the highest summits inside the county with at least 980 ft (300 m) of prominence, then the highest federal (GNIS) summits inside it when there are fewer than 5; each is the 3DEP top on a ~7 ft (2 m) window, or the NGS published height when a usable survey mark sits within 160 ft (50 m) of it (shown as published).
  • Towns: each town's typical elevation (population-weighted median of its own 2020 blocks at 1 arc-second); a town is listed when any of its 2020 residents live in the county.
  • Rounding: computed heights are rounded to 10 ft (5 m), or to 1 ft (1 m) under 100 ft; 3DEP is good to about a meter, not a foot. Published figures (NGS survey heights) are shown as their publisher gives them.
  • Datum: North American Vertical Datum of 1988 (NAVD 88). NGS plans to replace NAVD 88 with a new datum (NAPGD2022); heights will then shift slightly.
