rio grande source

[sprite]

Can anyone tell me approximately where the Rio Grande river has its source? I am curious to know what town is nearest that place.
Internet research has not been helpful nor have any of the terrain maps I have looked at. All I can see on the terrain maps is a river starting from somewhere near Zacero and snaking its way south between Naranjo and San Ramon then further south past Palmares before zig zagging all over the place on its way to the Pacific.
This is supposed to be one of Costa Rica’s important rivers and it is irritating the hell out me that I cannot find this info on my own.

Need to narrow down the region. CR does have topographic maps and I have purchased them in Montezuma. There is a web site http://costa-rica-guide.com/Topo.html. Go to detail maps and you can zoom in on a specific region, which shows the river systems.

Try Google Earth, the resolution of the coverage in that area looks good enough to trace it up to the source.

Google earth is one I have looked at. The terrain map shows the low creases but is not clear as to where the river has it source area. It looks like it could be in any one of three directions from the town of San Juanillo.

The satellite map for that area is incredibly detailed and I can even make out the flat build site on my property but is not much help finding the river source area. The river is mostly covered by large tree tops and further north the path to the river gets lost.

I am assuming the river gets its water from mountain streams in a wide general area so water sources would be many springs. I also note that most of the mountain rivers and streams have water with a bluish-greyish tint. I read that this is due to volcanic rock particles disolved in the water.

There are no roads near it from that point forward. I suppose that is a good thing since nobody would be dumping trash from the road as they have done around the bigger cities.
