I have divided the season into
1) Pre Isaias,
2) Isaias affected incubation, and
3) Post Isaias.

1) Nests 9-14 were excavated on I-day because there had been hatchlings or signs of hatchlings. So all nests 1-14 had survived the June weekend of 16 inches of rain and while success wasn’t the greatest, they were all in the water

2) Nests 15-62 were all in the ground on I-day. Day after the storm some were still marked, some were located by visitors, some were located by animals, some were barely under the sand, some were so deep we nearly lost the excavators, some nests were lost. Some of the lost were washed away. Some of the lost were just never located. Some of the located nests had less eggs after the storm than before. Some of the lost were probably just too deep for us to find. Some were so compacted in the sand that hatchlings were odd shaped.

3) Nests 63-65 were laid after Isaias but nests 63 and 64 were overwashed during the king tides Sept 20-23. Nests 66 and 67 were wild nests that were high in the dunes and survived all the elements.
