Weird terrain error on Google Earth

Odd terrain error I found on Google Earth in eastern Oregon. The black line near the middle of the image is a railroad and the red line is just some unrelated direction data. The odd raised section seems to follow a river. And yes, I've been through here multiple times in real life and I know that this error is not accurate.

Most likely the software misread the river as being much higher, maybe due to reflections of light from when the original picture was taken

The height data can come from various sources. Someone probably went down that river in a boat, or hiked it to get that height data, and it was considered (or could actually be) more accurate than the data for the surrounding area.

I recall people showing "proof" that something was going on in the Atlantic ocean because of weird hash marks in the sea floor where the depth was different than the surrounding areas. Turns out, that data had come from a seafloor-depth sampling mission in which the boats actually patrolled the area in a grid.
