while hiking marys mountain in nevada i noticed that the caltopo USGS map
tile seems to be incorrect.

marys mountain is at 40.735667, -116.263151

you can see the issue at the boundary of the quad, or if you flip to your
mapbuilder topo layer instead.

i dug through the USGS website a bit and i noticed that their 1989 map is
wrong as well... but the 1986 map seems to be correct.

1986 map is here:

compare:

    thanks!

    hey i found another error, this one in boulder beach, NV quad.

    the 1973 tile is a satellite photo https://www.sciencebase.gov/catalog/item?scheme=gda&type=id&key=5567118

    the 1970 tile is a topo map https://www.sciencebase.gov/catalog/item?scheme=gda&type=id&key=5567116
