COLUMBIA RIVER GORGE - Five people were injured along a Columbia River Gorge trail on Friday when a rock slide came down on top of them.

The incident happened around 3 p.m. at Horsetail Falls, which is located just a few miles east of Multnomah Falls.

According to a couple who was on the trail, they had just warned a group of five people that rocks were falling in the area and when they got about 30 yards away, they heard screaming.

The five people included a father, mother, their two children and friend.

The father, who reportedly sheltered the children to try to protect them, sustained the most injuries.  He suffered serious trauma to his head and spine.

The mother sustained serious contusions and abrasions.

The couple's two children, a 10-year-old girl and a 4-year-old boy, were hurt as well.  The girl's leg was injured and the boy ended up with minor cuts and scrapes.

Another 10-year-old girl, who is a friend of the couple's daughter, ended up with an injured wrist.

Officials are checking above the slide area to see if anyone else was injured along the trail.  A second rescue is under way at nearby Triple Falls, where a man reportedly fell about 40 feet.
