Grand Canyon National Park rangers were searching Monday for a woman who disappeared from a river trip on the Colorado River.

Park representatives say that on Saturday the Grand Canyon Regional Communications Center received a call via satellite phone from a private river trip reporting that a member of their party was missing.

Initial helicopter search operations were begun and rangers were flown to the scene where it was determined that 21-year old Kaitlin Anne Kenney of Englewood, Colorado, had last been seen Friday night at her group’s camp located at river mile 134.5 near Tapeats Creek (on the north side of the river.)

On Sunday, rangers continued their investigations and helicopter search operations while ground-based search teams searched the Tapeats and Deer Creek drainages, Surprise Valley, and along the Colorado River.

On Monday, based on their investigations and search efforts so far, ground-based search teams were intensifying their search efforts in the Tapeats Creek area.

Ms. Kenney is described as 5-feet 5-inches tall, weighing 125 pounds. She has brown hair and brown eyes and was last seen wearing a tan knee length coat, hiking boots, rugged tan pants, a long-sleeved grey shirt, multi-colored scarf and black knit cap.

If you think you have seen Kaitlin Kenney since Friday, January 11, or that you may have information that would aid in the park’s search efforts, please contact the Grand Canyon tip line at 928-638-7767.
