Determining the inventor of snowmobiles can sometimes be tricky, as different sources may attribute the invention to different individuals. In this case, there are conflicting claims between O.C. Johnson and Carl Eliason.

To find out the most accurate information, it is advisable to consult multiple sources and weigh the evidence from each. While the first site you mentioned credits Carl Eliason as the inventor, the second site mentions O.C. Johnson.

It is always a good approach to cross-reference multiple sources, especially when there are conflicting claims. In this case, it seems that both individuals have been associated with the invention of the snowmobile, but it may be more appropriate to consider them as key contributors in its development.
