We were also relieved to wake up this morning to find that we had not been swept away by a lahar. While I was finishing my hour on the internet, Walter read all the notices on the walls and pointed out that we were in a high risk lahar area, which was not comforting as we were about to go to bed. According to the instructions, on hearing a siren we have to dress warmly, gather up our valuables and sleeping bag and head for the safe area, which is a ten minute walk away (no driving vehicles). There is only a 10 minute warning before the lahar reaches you so not sure how you can do all of the above and still get to safety!
We had a very interesting day (as always). On the 2 ½ hour walk we travelled through a mountain beech forest and then climbed very steeply alongside a stream which ran over red and yellow rocks. The rocks are coloured by deposits of iron-oxide clays from upstream swamps. The stream eventually turned into rapids (Silica Rapids) and when we reached the place where the stream comes out of the cliffs there were creamy white terraces. We also walked (on boardwalks) over swampy areas of wire rush, tangle fern and red tussock plus a higher altitude tussock-covered lava flow.
