Squall over Chalk Lagoon
Storm
A sharp squall swept across Chalk Lagoon overnight: sea winds shifted and turned the calm surface into choppy white crests, flinging small debris from the cliffs. For an area usually marked by still waters, instruments recorded a rapid pressure jump and a marked gust front within half an hour.
The group of Pteranodon longiceps that typically skim the gentle currents changed tactics: many dropped low over the water, holding close to wave troughs and beating wings near the crests to maintain position rather than making long foraging flights. Younger birds were seen retreating earlier to cliffside shelters on the Ptero Cliffs.
Along the surf line, the Diplodocus longus migration found its pace disrupted; the column tightened into denser groups and edged farther from the surfline where waves were less erosive. Field checks reported minor scouring of shoreline plants, but no injuries to the large herbivores were noted.
Park teams raised observation levels: mobile patrols altered routes to avoid cliff-slip zones and increased behavioral monitoring of lagoon birds and the moving column. By morning the squall had begun to subside, but heightened coastal surveillance remains in place for the next 12 hours.
