Recent high surf pushed water into the mouth of Mission Creek, creating a quicksand effect.
Firefighters were called to the area to rescue a 73-year-old woman visiting the area from Ireland who got stuck in the sand.
When firefighters tried to pull her out, they got stuck too.
They ended up laying a ladder flat along the ground, walking on it to rescue her.
Afterward, they filled the area with regular, dry sand to prevent anyone else from getting stuck.
