The call came in:
Ã¢â‚¬Å“It was a little before 6 p.m. when she called. She indicated to me that she was lost in the mountains, and she indicated that she was on foot,Ã¢â‚¬Â Kerry Koppes said. Ã¢â‚¬Å“She thought she was in the proximity of what she described as GreyÃ¢â‚¬â„¢s Trail.
Koppes figured she was talking about Greyrock Trail, and he estimated she was as high as 9,000 feet.
The womanÃ¢â‚¬â„¢s cell phone was equipped with a wireless phase 2 technology. Koppes said that gives the center a latitude and longitude and location of a tower. He found the tower from where the womanÃ¢â‚¬â„¢s strongest signal was picked up.
Ã¢â‚¬Å“Anytime you pick up a cell phone and you dial youÃ¢â‚¬â„¢ll hit multiple towers,Ã¢â‚¬Â he said. Ã¢â‚¬Å“Your signal strength will always be strongest into one particular tower, and thatÃ¢â‚¬â„¢s usually how your call gets routed. ItÃ¢â‚¬â„¢s the first time IÃ¢â‚¬â„¢ve had the experience with this system in a situation like this, and we had a save like this.Ã¢â‚¬ÂKoppes said he got the latitude and longitude based on the triangulation from her phone, and he was able to take that data and plot it into the centerÃ¢â‚¬â„¢s computer maps.
