Did you also measure the temperature in the shade of tall trees along the beach, I'll bet it was significantly cooler than the 109° you measured way back in the bush to illustrate the difficulties you guys faced. I see that it would be very daunting for Earhart to hack her way back through the scavola, especially without machetes, so it makes much more sense that she would have established a camp right on the beach under the shade of trees or a parachute where the temperature should be only in the 80's due to proximity to the ocean and ocean breezes.
The thing is however what were she or they relying on for water.
Quote from Gary LaPook and Malcolm McKay
You people don’t seem to understand how important it is for many Tighar members to think up reasons why Amelia could not get to an opening or to the beach, take off her blouse, and wave it over her head, and be seen by any one of the 3 airplanes and 6 navy aviators looking for her in the approx 28 minutes they were flying over Gardner island.
The only real answer is if Amelia was already dead
( or dieing ), or if Amelia was not on Gardner, that would ruin the
‘castaway of the seven site’ theory, which would be greatly unsettling to many as then who could have opened the clam at site seven in the
American way ? (certainly not any of the 25
American costies in their years at or near this site), and then there are the many fire remains to be accounted for. If AE didn’t light these fires who else could have ? (
again certainly not the costies, or the settlers, or others ) But the kicker is the turtle bones and birds eaten,,,, that by itself could only be the work of AE.
We have to keep the legend of the castaway at the seven site alive, which means only one of two possibilities: some variation of the navy guys incompetence or Amelia finding on a ½ mile wide island some place to hike to, at just the right moment, that she can’t get out for the next approx. half hour.
