On my way back to civilisation from Tama Lakes, I decided to take a detour to visit Saddle Cone, a small isolated crater on the northern slopes of Ruapehu. You can see the tilted rim of the cone in the centre of the photo:
In spite of its small dimensions, Saddle Cone produced a huge lava field
that spreads out over an area of several square kilometres. These lava flows are visible in the distance.
