South of Haast, the coastline turns westward along a 24 kilometre, gently curving bay to Jackson Head. This headland provides shelter from the prevailing wind direction, and here a fishing harbour has survived since the early pioneer days of seal hunting. Jackson Head also marks the southern end of the west coast's narrow river plains. Beyond this point, the steep mountain ranges plunge directly into the sea - the first of the deep glacial fiords is just 60 kms away.
