PHOENIX --

According to the National Park Service, several lightning strikes have sparked a total of six fires along the North Rim of the Grand Canyon National Park and another fire on the Rim of the Tonto National Forest.

There are no fire-related road or trail closures on the North Rim at this time.

The first fire, dubbed the Point Fire by the NPS, was reported on Tuesday and is located about two miles north-northeast of Highway 67 and one mile south of the park's boundary. The 2-acre fire was contained due to its close status to the Saddle Mountain Wilderness, and will be in patrol status until it is declared out.

A release provided by the NPS stated that 5 additional fires were reported on Wednesday, including the Aspen Fire, the Angel Fire, the Butte Fire, the Poplar Fire and the Thompson Fire.

Aspen Fire

The Aspen Fire is located on the Walhalla Plateau, east of the North Rim developed area. Authorities said mixed vegetation -- consisting of ponderosa pine, fir, Mexican locust and dead and downed logs from the 2001 Vista Fire -- is burning about one mile southwest of Vista Encantada on Cape Royal Road.

Fire managers said the Aspen Fire has been very active in the past 36 hours, has grown to approximately 60 acres and has produced smoke that is visible from the North Rim developed area. The smoke has been settling into the Bright Angel Canyon after sundown, authorities said.

According to fire managers, the Aspen Fire is expected to burn for several weeks and will be managed as a "resource benefit" fire, meaning it will be allowed to burn naturally to help native fire-dependent ecosystems. Letting fires burn reduces the risk of larger fires, recycles nutrients, and allows for greater diversity of wildlife.

Angel Fire

The Angel Fire is located north-northwest of the North Rim developed area and about two and a half miles west of Point Imperial.

According to the NPS release, the fire is smoldering and creeping in dead and downed logs from the 2000 Outlet Fire.

Fire managers said the Angel fire is only a tenth of an acre in size and is expected to be managed for resource benefit as well.

Butte Fire

The Butte Fire is located in the inner canyon, east of the Walhalla Plateau and southwest of the Nankoweep area.

Officials said the fire spans roughly 5 acres and is burning in low, woody vegetation.
