Where the heck is the Litani River?

Is it really that complicated? Apparently, yes.

NYTimes: some 15 miles north of the border

Reuters: some 20 km (13 miles) north of the border

CNN: Leaflets urging residents in southern Lebanon to leave their homes and move north of the Litani River, 25 miles (40 kilometers) from the Israeli border

AP (carried elsewhere): They said they could easily dash inland to the Litani River -- their final objective about 18 miles from the border...

The depth of Israel's planned penetration into Lebanon is rather important, no? Seemingly, it would affect the number of Israeli towns that would be in the range of various Hizbullah weaponry. Can no one pull out an atlas (or download one) and measure the distance? Am I missing something here?

And if the Litani varies in its distance from the Israeli border, wouldn't it make sense to mention that fact and perhaps supply a range of distances that reflect its position relative to Israeli territory?

C'mon, media people. Some among you are being either lazy or stupid.
