A sudden downpour near Terry, Montana on the evening of June 19, 1938 caused a flash flooding of the Custer Creek that would lead to a disaster before the night was over. Earlier in the day, a track walker was sent out the check the rail lines near Custer Creek which was located near the town of Terry, Montana. After his inspection, he reported to his superiors that the conditions were dry, and there were no problems with the tracks.
That was true at the time, but within a few hours, a sudden downpour overwhelmed Custer Creek. A small winding river, Custer Creek runs through 25 miles of the Great Plains before depositing into the Yellowstone River. Small streams like Custer Creek are prone to flash floods, because they don’t have the capacity to handle any big influx of water, and their banks can quickly and easily be overtaken during heavy rains. As the water came rushing down stream, it washed out a bridge used by the trains. When the Olympian Special came through, it went crashing into the raging waters with no warning. Two sleeper cars were buried in the muddy waters. The night was pitch black seriously hampering rescue efforts. In all, 46 people lost their lives, and 60 others were seriously injured. The rear cars stayed above the water, but scores of passengers were seriously injured. They could not be evacuated until the following morning. I can’t even begin to imagine how awful that was.
That was a tough week for Montana. Just a few days later, Black Eagle saw “torrents of water” that floated furniture in the house of Sam Tadich, the sheriff had to help a rescue effort, the road to Giant Springs washed away and water was up to cows’ flanks around the Sun River. Havre’s worst flood came in June 22, 1938, when a cloudburst in the Bear Paw Mountains sent out a wall of water. Ten people were killed. Floating train cars were wedged under the viaduct, 10 miles of highway were underwater between Laredo and Box Elder, with a bridge washed out, the Havre Daily News reported. Rain is a good thing, but too much rain, coming too fast can devastate an area, especially one with a creek or river, in a very short time, and for Montana, it was a very rainy week, making it a very tough week.
