The 12-year-old Turner boy who was hurt at Black Mountain of Maine in Rumford on Sunday remains under close eye at a Portland hospital, a person close to the family said Thursday.

Eli Leavitt was skiing with friends Sunday after he completed racing for the Chisholm Area Race Team when he went off the Lower Allagash Trail and ran into trees in the woods. He was treated by Black Mountain crew members before being taken to Rumford Hospital and airlifted to Barbara Bush Children’s Hospital in Portland.

“Eli received several CT scans, X-rays and MRIs, and doctors have determined that his injuries are more significant than they originally thought,” Adam Dube said.

Dube, who coached Leavitt in youth lacrosse and soccer, helped the boy’s family create a GoFundMe fundraiser. The money will go directly toward medical bills and helping the family pay other expenses.

“These are life changing circumstances that are going to bring extraordinary financial hardships to the Leavitt family,” Dube wrote.

As of Thursday afternoon, the GoFundMe for Leavitt had raised more than $30,000.

In addition, owners of Lost Valley Ski Area in Auburn announced they will donate $10 from every lift ticket sold Thursday and Friday, as well as Baxter Brewing Co. Race Night fees, to the family’s medical bills.

“Eli and his family have strong ties to Lost Valley and the Maine ski racing community, and right now they need our support,” Lost Valley owners said in a Facebook post. “The ski community is strongest when we come together. Let’s show Eli and his family how much support they have behind them.”
