the maerkers ,as you noticed are fixed, let you know where you are. They are reflective so they can be used at night along with a lake map. At times there can be floating buoys the do the same thing. The fixed marker are always in their spot but buoys can break loose, these should be reported to rangers
Gray point is one of the better kept secrets at LBL. I am extremely happy that it can not be reached by cars. There used to be a TIKI Totem out there and we referred to it as TIKI Point.
We were so excited to finally make it out there! We pour over maps and sat images when trip planning, and that spot had been on our list for awhile. It's a fun drive, but yes, a little rough. Looks like it could get pretty muddy too. Beautiful spot! We were wishing we had thrown our chairs in the truck.
I found this cool pdf with illustrations. It looks like they do more. The pdf also shows what different buoys mean. It won't let me paste it here, but I just Googled what are the red and green signs on waterways. Thanks for sharing all your adventures
