about 2-3 miles to the east of TMHSC on the 120, north side of the road. GE coordinates are 37°52'43.66"N 119°17'20.54"W
It may be seasonal, but I recall having seen it every year for years, and I've never heard it called anything.
Finally had the time early yesterday morning to stop and take the time for some decent pics, and I don't know what to call it.
Thanks!
