Investigators at Mount Baldy have wrapped up their probe at the dune, but won't know for sure for several weeks what caused it to collapse.

Earlier this summer, 6-year-old Nathan Woessner fell into a hole in the dune and was buried in sand for several hours.

The environmental protection agency scanned 42 acres of the dune to look for more traps.

Mount Baldy remains closed pending the results of the investigation.
