SANTO DOMINGO, Dominican Republic?Two U.S. scientists lost in a mountainous park for a week were rescued by a Dominican search team and were recuperating Thursday from exhaustion, officials said.

Patrick Martin and Olivia Duren got lost on Feb. 21 in Armando Bermudez National Park, site of Pico Duarte, the highest mountain in the Caribbean at nearly 10,500 feet.

Martin and his assistant Duren, both from Cornell University, were researching a rare pine tree, Pino occidentalis, which grows in parts of the Dominican Republic. Fog and fatigue made them lose their trail, said Radhames Lora Salcedo, director of the country’s emergency agency.

When found, the scientists had not eaten for two days and were suffering from fatigue, diarrhea and minor scratches, Lora said.

More than 60 people and a helicopter participated in the rescue efforts.
