The joy of 32/33 F and precipitation

We should have taken a look for that one along with the Missouri, Iowa, Nebraska corner when we did a hydrographic survey of the MO River from Rulo, NE to Sioux City.  I think we saw something for the South Dakota, Nebraska, Iowa corner but didn't realize what we were looking at from the boat.  Our project stopped about 500' past it.
