A 103 year-old woman has just shown the world that age really is just a number by signing on to be a junior ranger at the Grand Canyon National Park in Arizona.

Rose Torphy is a mother of three and great-great-grandmother of 10 who first visited the park 34 years ago, and decided to do so again last month.

“I started talking to people about the junior ranger program because it teaches kids to protect the canyon,” Rose said of her recent visit. “My parents taught me to care for the land, but not all the kids have that.”

Rose said that she first visited the park in 1985, back “when she was able to walk around,” but she still had just as much fun going there this time in her wheelchair, which allowed her to “go to the edge.”

Believe it or not, Rose is actually older than the park itself. The Grand Canyon was made a national park on Feb. 26, 1919, when Rose was already a toddler!

Participants in the junior ranger program pledge to protect the World Heritage Site for future generations and complete an activity book about the national park with help from the Grand Canyon Conservancy, which funds the program. Cheri Stoneburner said that her mother was so proud to become a junior ranger that she has not taken her pin off since leaving the park!

“She’s a spokesperson for the park now,” Cheri said. “Everywhere we go, people ask her about her junior ranger pin and she says, ‘You’re never too old to see the Grand Canyon!’”

“She is probably the oldest Scorpion in the 11 and above category,” Cheri added with a laugh.
