Long Significance Description:
The 1932 Snogo Snow Plow is eligible for the National Register under Criterion A for transportation. The plow was used on Trail Ridge Road, the highest continuous highway in the US and a major feature of the park, to open the road for tourists. The plow is also eligible under Criterion C in the area of engineering. Innovative for its time, the plow included then state-or-the-art features such as the use of an auger and blower to remove snow, the placement of all controls within a closed, heated cab, and roll up windows. The Snogo is a rare remaining example of this type of equipment, and has all of its original materials and components. The period of significance is 1932 – 1952.

Long Physical Description:
Vehicle is a 4 wheel drive plow, 1932 Model F, No. 107 painted orange. The gasoline engine (Number 15210) is a "Climax Blue Streak" R-61, inline 6-cylinder, valve in head, with a 6-inch bore by 7-inch stroke, producing 175 horsepower at 1200 RPM. Engine and its components actually sit behind the cab at the rear of the vehicle. Dual horizontal augers (with shear pins) in the front of the plow forced snow into an in-line rotor fan turning at 350 RMP. A 1931 catalog claims the plow could remove snow with a depth of up to 35 feet (probably not in one pass) and was capable of throwing the snow up to 100 feet on either side of the plow.

Other exterior features include original lights below the windshield, wipers mounted under a hood over the windshield, and two square windows at the base of the front of the cab. A large metal step on either side provides access to the doors of the cab, which sits approximately 3 to 4 feet above the ground. Interior features include controls that could be operated from inside a closed cab, windows that rolled up and down, and a heater mounted under the seat.

Width of the plow was deisgned to be 7 feet 10 inches to fit inside the garage of that day. There is a 125 gallon gas tank. The Snogo was also equiped with an eight speed gear box that resulted in speeds of 1/4 MPH in low and up to 25 MPH in high gear when not moving snow.

The Snogo Snow Plow was manufactured by the Klauer Manufacturing Company of Dubuque, Iowa, in 1932.
