Styaks Swamp
From Wikipedia, the free encyclopedia
Styaks Swamp is one of the volcanoes in the Auckland volcanic field, found in the suburb of East Tāmaki.
Geology
It erupted approximately 19,600 years ago[1] and formed a 250m wide explosion crater[2] with a surrounding low-profile tuff ring of approximately 400m diameter from crest-to-crest[3]. It is located north of Green Hill.
Styaks Swamp is one of a line of four volcanoes that lie in close proximity. Ash from Styaks Swamp overlapping lava flows from Green Hill suggests that volcanic activity moved from south to north; with Hampton Park being the youngest, followed by Ōtara Hill, Green Hill, then Styaks Swamp the oldest.[2] The lava flows of all four spread westwards.[2]
A lava flow from the volcano forms the southern boundary of the Pakuranga Creek, around Burswood Reserve.[4]
History
During the early colonial era, the volcano was a park of John Styak's farm.[4] The crater once contained a swamp but is now covered by industrial development.
