PHOENIX — The Siphon Fire, which has ignited in the Superstition Wilderness, has rapidly expanded to 15,876 acres. Officials from the Tonto National Forest announced that the fire was human-caused, although the specific cause remains under investigation.

In response to the fire’s progression, authorities have evacuated the Canyon Lake and Tortilla Flat regions, primarily in remote areas northeast of Apache Junction.

A “GO” evacuation order is now in effect along State Route 88 (Apache Trail), commencing at mile marker 203.5 at Needle Vista. Meanwhile, residents situated east of Mountain View Road and west of the Tonto National Forest have been placed under “SET” status, as per directives from Pinal County.

Additionally, a “READY” advisory has been issued for communities south of Tonto National Forest, especially in the Gold Canyon area. This includes areas between Broadway and Southern avenues and between Geronimo and Barkley roads. The advisory also applies to residents in Apache Junction.

Firefighting efforts are hampered by the area’s rugged terrain, limiting accessibility for ground resources. Currently, two engines and a Type 1 helicopter are deployed to combat the blaze.

Residents and visitors in the East Valley have been urged to avoid the First Water, Boulder, and Siphon Trails while firefighting operations unfold. Lost Dutchman State Park is closed due to the fire activity.

Footage captured by Sky12 on Thursday night displayed the mountains engulfed in flames.

Local resident Joanne DeSena shared a photo of the fire’s impact from a distance, highlighting the ongoing situation in the Superstition Mountains.

Fire updates will continue to be monitored closely, with officials committed to providing timely information as the situation evolves.
