Scenic Sunday: Stone walls at Otuataua


Out at Mangere, at the Otuataua, there were miles and miles of stone walls. Some of the have crumbled, and farmers put an electric wire to prevent cows from crossing, and also deter adventurers like me.

The 100 ha Otuataua stonefields nearby are one of the few remnants of an original 8000ha of volcanic stonefields in the Auckland area, all intensively cultivated by early Maori settlers. The stones flung out in successive volcanic eruptions were used to demarcate garden plots and to warm the soil, extending the growing season for tropical crops like taro and kumara by one month.

Great picture, Ann... Can you imagine how long it must have taken them to build those stone walls???? LOTS and LOTS of hours I'm sure.

So it is made from stones from volcanoic eruptions? How cool, and finding a good use for something likt that.

I can visualize stones from volcanic eruptions being used for fences, but having them warm the soil is something I never even considered.

How would the stones warm the soil?
