"I can see tracks being inspected," she said. "Looks like surveyors and railroad officials."
By noon, any inspection activity was apparently over. There were no surveyors or other BNSF staff on site.
The tracks show clear orange paint markings beginning 100 yards north of the southern end of the lagoon. The marks are on the tracks going north towards the tunnel.
BNSF officials have been contacted for comment.
