The National Park Service said in a news release that a 26-year-old woman has died after falling in a canyon at Zion National Park in Utah, US, and her body was recovered Sunday evening from the Mystery Canyon.

According to visitors, the woman was canyoneering alone and fell 15 to 24 meters Saturday afternoon. Crews launched a search and rescue effort that closed various areas of the park.

A helicopter was sent to rescue the woman but was unable to pull her out “due to the steep, narrow canyon walls,” the park service said in the release. Medics later reached the woman before she died a short time later.

The woman had injuries consistent with a high-elevation fall, park officials said. Her name was not immediately released.

The woman was said to have been “canyoneering” — a practice or sport of following a body of water through a canyon by walking, swimming, rafting, climbing, rappelling or other similar means.

The National Park Service and the Washington County Sheriff’s Office were investigating the death.
