The grassy fields of Chicago's Grant Park were muddied and riddled with tire tracks days after the city's flagship music festival.

Lollapalooza took over the park for four days at the start of August, drawing hundreds of thousands of music fans from around the world.

Massive crowds trounced on the lawns during the festival and the deconstruction process of the many stages and other festival sites has turned the once green grass into a muddy mess.

Lollapalooza event organizers are responsible for restoring the park back to its pre-event condition, according to a spokesperson Chicago Park District. A walk through with the organizers is done by the park district to determine damages.

The park district did not provide a timeline for the restoration process.
