NMB Nest #4--The nest that kept giving and giving and giving....

NMB Nest #4, 42nd Ave N, Cherry Grove, was located by Arlene.  A very stormy morning, Arlene saw the mother on the beach around 5:30 AM.  She watched as she finished laying and crawled into the ocean.  A major storm blew through, chasing all off the beach.  When Volunteers were finally able to get back, the rain had erased most of the mothers tracks.  But We know where she had laid.  A good nest, just above the HTL, close to the dunes, nest was left where it was, opening the egg chamber just long enough to remove the top egg for DNA Study.

 
August 23, 54 days later, While checking the nest around 7AM, Maddy notices a ghost crab digging into the middle of the egg chamber.  Sand falls and hatchlings are visible on the surface. 
 
 When the lights hits the hatchling, many wake up and crawl out of the hole and make the dash to the ocean.  Soon, no visible turtles are in the nest.  That nights, several small "boils" occurred with more hatchlings emerging in intervals of 30 to 40 minutes apart.  Inventory is started 4 days later, but quickly halted when more hatchlings are fond just under the sand.  Around 11PM that night, more hatchlings emerged, all going to the water.  When Carol checked this nest two days later, she found fresh hatchling tracks.  Nest is Inventoried again on Thursday August 29th.
 
 
For the second time, crowd starts to gather
