I've just added a whole load more lakes in southern Peru from the aerial photography. The more I search, the more lakes I find.....I've gradually been working north, but I reached a point where my wrist was aching so much from repeated mouse clicks that I had to stop. There are many hours more work to be done here, even to reach the same latitude as Lima. It's a fascinating landscape and occasionally I come across a settlement, but usually I have no clue what it's called so it becomes an anonymous town, for the time being.
