"I do not think that I will ever be able to describe terror properly," she wrote.
The event felt like an eternity, Elisha said, but could have been just minutes.
The wolf began to pull Matthew away when a nearby camper, Russ Fee, heard the family scream and jumped in to help.
The charge said he immediately regretted kicking the wolf, but that caused the animal to release Matthew and jump out of the tent. Matthew soon followed and the two started screaming and throwing stones at it.
Meanwhile, Elisa and the rest of the family ran toward Fee's minivan to safety.
Rispolis finally went to a nearby hospital, where Matthew's wounds were treated. Elisa wrote that he had puncture wounds and laces on his hands, but he is doing well. Matthew was the only one injured in the attack.
"It could have been so, so much worse, and we just feel so grateful that we are all still sitting here as a complete family," she wrote.
Elisa Rispoli did not respond to a request for further comment.
This is the first time a wolf attack is reported in a national park
Events such as these are extremely rare. This is the first reported wolf attack on people at a national site, according to Parks Canada, although there have been attacks in provincial parks: one in British Columbia and one in Ontario.
Lesley Matheson, a spokeswoman for Parks Canada, said no significant attractions or food was found inside or near the tent.
The campsite was closed for a few days while Parks Canada investigated the incident. It reopened Monday after park staff tracked and killed the animal and confirmed it was right through DNA testing.
It's unclear why the wolf was attracted to this family, Matheson said. Veterinary tests confirmed that the wolf was in "poor condition" and was nearing the end of its life, which was probably a contributing factor in its behavior, Parks Canada said.
The wolf was underweight for its age, only 78 pounds compared to the usual range of 1
