[83] In the vicinity, the Skeena River includes rock outcroppings, gravel and sandbars, wetlands, sloughs, and islands.

Over 25,000 years ago, the river cut through glaciers to create the benches (stepped terraces) and deposited well-drained sandy loamy soils suited for agriculture.

[177] In 1936, high water washed out four timber spans of the trestle approach on the south side of the bridge, which required the installation of a temporary catwalk.

On realignment, many new spans and concrete piers were added, a new hardwood deck was installed, and the approaches changed.

The world's tallest pole, 49 m (162 ft) long, was cut in Terrace and stands in New York City.

During World War I, the Terrace Hotel at Kalum Street and Greig Avenue was converted into a temporary hospital, where patients from the Spanish flu epidemic were treated by volunteer nurses.

After the war, several doctors practised from a small wooden medical building near the foot of Kalum Street, which Dr. Traynor built during a brief return to Terrace in 1919.

During World War II, a 300-bed military hospital was erected on the bench, on property now partly occupied by Terraceview Lodge.
