A teenager died after a terrible hiking accident in a local park.

Family and friends of Heather Garza said she loved the outdoors. She was hiking with a friend at O.P. Schnabel Park Saturday when she somehow slipped and fell into a 30-foot ravine.

Heather is described as a selfless girl, who was beautiful from the inside out. The 18-year-old graduated from Taft High School last May.

"She went to put her foot on the ledge and her shoe slipped," said Heather's aunt Melba Smith.

Heather fell backward and was knocked unconscious. She was rushed to University Hospital, but did not survive.

"In her short life, she made a difference in hundreds of lives," Smith told News 4.

Now, even in death, Heather continues to give and make a difference. She made it clear to her family if anything ever happened to her, she wanted to be an organ donor.

Heather's family believes at least part of the park is dangerous. They want the city to close some of the trails there.

For now, they're trying to focus on the good that's come from the tragedy. Heather's organs and skin will help more than 100 different people.

A memorial is planned for Heather on Saturday. Her family is asking anyone who wants to honor her to donate to the Humane Society in Heather's name.
