Watch: Crews rescue 70-year-old grandma who tumbled down hill in Washington

AUBURN, WA (KTRK) -- A 70-year-old woman had to be rescued after she tumbled down a steep hill while walking her dog and two grandchildren, ABC affiliate KOMO-TV reports.

According to Valley Regional Fire Authority officials, the woman fell roughly 150 feet down the steep hillside, just above the White River. Her two grandsons, ages 7- and 11- years old fell also. However, the 11-year-old boy was able to climb up the embankment and call 911.

"Is my grandma going to be okay? Is she going to be okay? Then I was worried about (Ian) because he was slipping," said Kaden, 11.

Rescue workers ended up saving the boy's brother and grandmother. Both boys were unhurt. But, their grandmother suffered a broken back and had to be taken to a hospital. She's expected to be okay.

Meantime, the boys' mother, Robin Holt, says she is proud of the way her son Kaden handled the scary incident.

"I'm very proud of him," Holt told KOMO-TV. "I told him how I proud I was of him for responding quickly and taking charge of the situation."
