This might be what your looking for, except when most of us are giving coordinates we are using degrees-and minutes where this chart is decimal degrees :example: the post might read was at 27.6 x 21.9 , which in the central basin would actually be 41 degrees 27.6 min x 82 degrees 21.9 minutes[most of us just use the minutes]
To convert to decimal degrees take the minutes 27.6 and divide by 60 which would be .46 and 21.9 divided by 60=.365
41 degrees 27.6 minutes = 41.46
82 degrees 21.9 minutes =82.365

in this case would be the Vermilion dumping grounds

Cursor location is displayed on bottom of chart in decimal lat. long
