Connecticut at a glance
Connecticut's high point is a spot on a hillside - the actual summit of Mount Frissell is in Massachusetts.
source ↗Connecticut's central valley is lined with dramatic traprock ridges of ancient hardened lava.
source ↗The state faces Long Island Sound, a sheltered estuary rather than the open Atlantic.
source ↗Connecticut is one of the smallest states, yet spans hills, valleys and coast.
source ↗The highest true summit standing wholly in Connecticut is Bear Mountain, not the state high point.

Highest and lowest points
The highest point of Connecticut, 725 m, is not a summit at all but a spot on the south slope of Mount Frissell - whose actual peak lies in Massachusetts - one of the few state high points that is a hillside rather than a mountaintop.
source ↗Mount Frissell (south slope) is a border summit: its peak lies just outside the generalized Connecticut boundary, so the highest fully in-territory land pixel in the model is 2,379 ft (725 m). The headline figure above is the surveyed elevation of the recognised national high point.

About this map
The terrain is rendered from the Copernicus GLO-30 digital elevation model (ESA), masked to the US-CT boundary from geoBoundaries (gbOpen). Elevation statistics are computed directly from the model; peak names and researched facts are sourced and cited. See the methodology for the full pipeline.
Our area-weighted mean, computed from the Copernicus GLO-30 model, is 489 ft (149 m); the figure commonly cited elsewhere is 492 ft (150 m) (U.S. Geological Survey). Connecticut's mean elevation is about 150 m; the page reports the area-weighted figure computed from the Copernicus GLO-30 model.
