Pressure

endurance_night_pressure

“The blizzard has ceased. There are new lines of pressure along the edge of the great frozen lead to the north (astern of the ship). The ice of the frozen lead, about a foot thick only, has cracked along an almost straight line for a mile or two and the edges have ridden over each other for a distance of about 10yds, forming a long low bank of piled-up ice blocks and fragments. It is these banks that are called ‘pressure ridges’, or often simply ‘pressure’.”

ā€” Thomas Orde-Lees
