CLARKSVILLE, Ind. (WHAS11) -- Multiple fire departments worked for nearly four hours Thursday morning to get a massive fire under control at a Clarksville salvage yard.

It started at Kenny's Imports on McCullough Pike around 6:30 a.m.

Luckily, nobody was hurt.

WHAS11's Sara Wagner tweeted these pictures from the scene and SKY11 was over the fire as well:

"It was crazy because we thought people were just shooting guns. Come to find out, Kenny's is all up on fire," neighbor Bobbie Coombs said. "We feel good. As long as we're all alive and okay, it's all that matters to us."

There are surveillance cameras set up all over the property at Kenny's Imports. When the owner thought he saw something on there Thursday morning, he called his employee, Dennis Money, who was working on the house next door. Money walked outside to see flames and smoke shooting hundreds of feet in the air and called 911 right away.

Firefighters had to deal with multiple challenges on the scene.

"There are many different types of pieces of equipment. There's probably well-estimated more than 100 cars involved," Clarksville Fire Chief Brandon Skaggs said.

Those piles proved problematic for more than just what's easy to see.

"With the cars being stacked on top of each other, that creates voids and spaces that's really hard to get to," Skaggs said.

On top of that, there are no hydrants in the area, which forced crews to bring in tanker trucks from all over Clark County.

"Clarksville, Jeffersonville, Sellersburg, Monroe Township, Charlestown, Utica, New Chapel [all responded]," Skaggs said.

Jeffersonville Fire also debuted its drone to help keep tabs on the fire from above.

The owner said he's been in business for 25 years. He said much of the damage is to shredded cars that were no longer salvageable for parts and a back building that housed forklifts, other equipment, and propane tanks. While he's grateful nobody was physically hurt, this is still very painful. He said it's not just the loss of the materials, it's all of the memories created after two decades of calling the spot home.

Neighbors reported hearing explosions throughout the morning, but firefighters said that could be from any number of things in the junkyard like tires, different car parts, and those propane tanks.

The official cause is still under investigation.

Firefighters say they’re still in attack mode, expect to be here for several more hours putting out hotspots & other trouble areas. @WHAS11
