A Brazilian woman who fell hundreds of feet while hiking on an active volcano in Indonesia and was unreachable for three days was found dead Tuesday, according to her family.

The woman, Juliana Marins, who was in her 20s, was climbing Mount Rinjani with a group, including a guide, when she fell Saturday morning, according to her family.

“With great sadness, we inform you that she did not survive,” said a post on an Instagram account set up by Marins’ family to publicize her plight.

Rescue workers had been able to reach her Tuesday, according to the Instagram post.

Indonesian authorities said Monday that a female Brazilian tourist, whom they did not identify, was on the mountain and had fallen about 1,600 feet. She was motionless, they said, citing drone footage.

On Tuesday, authorities were preparing to send rescuers in a helicopter, equipped with thousands of feet of rope, to reach Marins, said Muhamad Hariyadi, chief of the search and rescue office in the nearby city of Mataram.
