Waterfalls & Lava Floes Warning - going further is not recommended! Do not approach the volcano! But we could see a steaming cloud up ahead, promising views of molten lava. We looked right and noticed sulfuric fumes billowing up, bringing back warnings of “don’t get surrounded by lava”. As I looked left, I heard a yelp of surprise. Looking back – and then down – I found Paul hip-deep in pumice.
