On the southern side of Highway 11, just by the Volcano Village turn-off, there is a very dense under-story of firns (see also image below). The tree tops are ~12 meters high. The first image is a View looking towards the SE.

The second image is a close-up view of the firn under-story that is shown in the first image.

From here you can continue on to Site 29 or you can pick another point from the Radar Tourpage.
