The National Air Vigilance Service, the Coast Guard and the Red Cross launched a rescue operation by air, sea and land to find the missing man, who is approximately 30 years old.
At dawn on Saturday the hikers managed to make a phone call from a mobile phone and send some details on their location, which allowed rescuers to find them.
Since 27-year-old Alaskan Cody Dial went missing after hiking in Costa Rica's wild Corcovado National Park, his father has traversed the park, repelled down waterfalls and trekked illegal gold mining trails in an attempt to find him. But even after weeks with no sign of his son, Roman Dial, a legendary Alaskan outdoorsman, is not ready to give up.
Search-and-rescue teams wrapped up a final operation on Monday to find U.S. hiker Cody Dial, who disappeared in Costa Rica in early July. Search teams focused their efforts on the rugged Corcovado National Park, where Dial was believed to be hiking, but failed to find any clues as to what happened to the 27-year-old Alaska-native.
David Gimelfarb disappeared on Aug. 11, 2009. His parents, Roma and Luda Gimelfarb, travel to Costa Rica every year to continue the search. This is the fifth year since David's disappearance, and police say they still have no clues as to what happened.
Representatives from the U.S. Embassy are now in Puerto Jiménez, near the park's eastern entrance, to take over the search, accompanied by Dial's father, Roman Dial, a National Geographic explorer and well-known adventure sportsman.
Two flyovers and several ground patrols have failed to turn up any sign of 27-year-old U.S. hiker Cody Roman Dial, who is suspected missing in Corcovado National Park in Costa Rica's southwestern Osa Peninsula since July 22. There is no official record of the young Alaskan's entry into the park and it is believed that Dial, an experienced backcountry hiker, followed routes that are off-limits to tourists.
