Crews are tackling a wildfire affecting a large area of moorland near a well-known driving route through the Peak District.
Derbyshire Fire and Rescue Service was informed of the fire on Thursday evening, and said at 11:30 BST on Friday there were nine fire crews in attendance.
The fire service said there was a “significant smoke plume” causing poor visibility on roads in the surrounding area.
Police said the A57 between Glossop and Ladybower Reservoir had been shut in both directions while emergency services deal with the “large-scale” fire.

The fire service said it was working with firefighters from Greater Manchester, West Yorkshire and South Yorkshire, alongside partners from the Peak District Fire Operations Group including local gamekeepers, landowners, and Derby Mountain Rescue team.
The service added support was provided by several specialist vehicles including three wildfire units and a helicopter.
A spokesperson said: “The affected area is approximately 1,200m by 600m.
“Thank you to everyone who has called us regarding smoke in Glossop. This incident is causing a smoke plume which is currently affecting areas in and around Glossop.”
Anyone who can see or smell smoke has been advised to keep windows and doors closed, and people and motorists have been urged to avoid the area and to use alternative routes.

“Neighbouring moorland gamekeepers were tackling the fire throughout the night, some stayed all night and others are rejoining them this morning.
“The weather conditions today will only dry the moss out even more, moderate winds are moving the fire at pace.”
The group said gamekeepers dealt with 36 wild camping and open fire incidents last weekend.
The National Gamekeepers’ Organisation wildfire risk index has been moved to red for all moorland areas in England and Wales, it added.
