Rocky cliffs, dense forest, steep terrain and oppressive heat continue to be obstacles.

But those who love Jesse Farber say they won't stop looking for the Tamaqua man even though the official search was suspended late Saturday.At 10 a.m. Sunday, more than one dozen family members and friends turned out at the base of Sharp Mountain near Tamaqua Area High School to explore their options and hike up the north face, despite a daunting forecast of near-ninety-degree temperatures and high humidity."We're just going to scour the mountain," said Norma Jean Fritz of Jim Thorpe, Farber's mother, who touched bases with teams that had explored the mountain over the past three days."The searchers said there's an area that could be checked a little bit more," Fritz said.By the end of the day, nothing new had been discovered.Among those turning out to help were those closest to the missing 29-year-old: his brothers, including Justin, 26, who flew into Philadelphia on Saturday from Army Reserve training overseas."I was in Germany when I got the call," he said, still battling jet lag. "I felt helpless."Another searcher with deep passion for the mission was volunteer Harry Hahn of Tamaqua. Hahn knows Farber and his family."I went to school with him. I knew him since sixth grade," Hahn said.Even more, Hahn experienced a similar situation last year.It was June 2014, when Hahn's younger brother, Jay, went missing.At the time, Hahn searched the woods during intense summer heat. Ultimately, the body of Jay Hahn was found. He was the victim of murder.On Sunday, Hahn arrived with equipment to address steep climbing."I brought a rope, a harness and water. He may have fallen somewhere, and there are stripping pits you can't access even with a four-wheeler," Hahn said.Experienced volunteersAmong other volunteer searchers were Robert Bailey and David Hartranft, both of Tamaqua and both with extensive knowledge of Sharp Mountain, where they routinely hunt. Another is former firefighter John Foster, of Tamaqua, along with George Love, an experienced climber with detailed knowledge of the mountain.Bailey said crossings are a key."There are basically two crossings to get from New England Valley to this side. Then, there's a third crossing where the old Tamaqua dump site was located," Bailey said."I came here Friday and looked down both pits," said Hartranft, who intended to spend Sunday checking sites and paths that Farber might've been familiar with.He and Love climbed the mountain on Friday because that was the day other searchers took a break.Katrina Mehallic, Farber's stepsister, arrived early to help organize plans, helped by Tyler Caulkins.Joe Shamonsky of Hometown showed up to offer use of his four-wheeler, while Orwigsburg Street resident Michelle Breiner Brode provided water and opened the doors of her air-conditioned house to offer relief for those tackling the climb.Final contactFamily members have searched for Farber, who also goes by the name Jesse Rex, since late Tuesday when he went missing.The last contact from the father of two was a cellphone call made to his girlfriend in which he reportedly said he was in the woods at the rear of the school.The official search launched by police kicked in Thursday, running from noon until 8:30 p.m. Another eight-hour search was conducted Friday by family and friends, followed by Saturday's eight-hour operation by police and search and rescue teams, after which the official search was ended."We're not giving up," said one volunteer Sunday morning as he packed an ice-cold water and began hiking up a rocky lane.Rescuers with specialized equipment might return to further examine a deep hole.According to searchers, a response team from the Pennsylvania Department of Environmental Protection lowered a camera into one of the mine voids that dot the mountain."It went down 175 feet or almost 200 feet and the lens broke," said Hartz.That particular site received extra scrutiny because of potential clues spotted around the opening."The ground was disturbed as if someone could have slipped," he said.It's unclear if the hole is an abandoned mine shaft or a deep subsidence. One rescuer who spoke on the condition of anonymity said the hole could reach a depth of 500 feet, at which point there's an undetermined depth of water.Searcher Christine Ciardelli of Northeast Search and Rescue K 9 Division confirmed that search dogs were useful at that site and others."The dogs did pick up several scents of interest," she said.Deb Sardone of Pennsylvania Wilderness Search and Rescue said her group's involvement has ended for now."But we'll be back if they call us."The disappearance has generated plenty of discussion on social networks.Local resident Ann Marie Calabrese summed up the feelings of many with pleas she posted Sunday on Facebook:"Somebody knows something! Too many 'don't want to get involved' ... how would you feel if this were your loved one? No family is exempt from bad things happening to them ... no matter who you are," said Calabrese.Anyone with information is asked to call Tamaqua police at 570-668-5000 or Norma Jean Fritz at 570-449-3985.The family will continue to gather information that might lead to clues as to what happened.Jesse Farber has many loved ones.They want him back home.
