If you click the Lat/Lon link or the Topozone link for this page you will see that your current coordinates are off by a little. Several people have already commented on this in the comment section. Eric is right, the actual exact coordinates for Sperry Peak are as follows. If you try them out, you will see they are correct.
I don't know what happened but those are the first coordinates I listed. Different numbers were posted and I tried to correct them but.........Its been back and forth. It took this time.
Thanks
