Some downtown La Crosse businesses were evacuated this afternoon after reports of a natural gas leak.
Crews were searching throughout the area starting at around 1 p..m.
Authorities confirmed the smell, but have been unable to find a source. They say it stretched from downtown all the way south to Gundersen Lutheran.
Firefighters monitored buildings throughout downtown and no detectable gas was found.
The fire department says in the past, an odorant added to natural gas, mercaptin had been accidentially released in the area "and created similar scares." The odor was gone by 2 p.m. and no other reports were made to dispatch.
