We are very grateful to the National Park Service for once again taking us behind the velvet ropes – this time at Rainbow Bridge. NPS is busy making a vibration study of this geological wonder. Are the numerous aircraft overflights and the noise they create detrimental to the site? We hope to help them make a determination by capturing then modeling the site. This past weekend we toured Rainbow Bridge with NPS rangers in order to plan the capture phase we hope will take place later this winter.
