It’s a funny thing to admit to being but the waters are rising fast and we are dangerously close to the Solimoes (Amazon) where flood waters flow into the forest like a bath tub overflowing with muddy brown water.

This means much slower progress whilst walking; wading through dark flooded forests up to our chests, and longer evacuation times should we need to escape fast in an emergency. We've done one Amazon flood season in Peru already but the scale of the river here is HUGE in comparison and the distance we need to put between us and the main river is much much further. Here the Amazon looks like a big sea of milky tea: you can look in several directions and not see the other side at all it is so massive.

This is all made worse by the mistake I made over the Google Earth "road" that turned out to be a tangled overgrown oil pipe line cutting. That's the only reason we've come back so close to the main river channel at this time of year. Cho and I may pay for my error over the next month as we battle to find hard ground to walk on again. This month and the next the waters, stocked with caiman and piranhas, will be rising and falling so we need a bit of luck to escape the worst of it. If not - camping above water may become necessary and life will get rather uncomfortable.

Cho's as relaxed as ever but he doesn't study the maps - he just walks and sings. I'm anxious - but that's a wonderful emotion compared to boredom - so I'm not complaining.
