They knew that a cycle of 365 days had passed. And this period of time was extremely consistent and repeatable. And they called that cycle a “year”. But they didn’t necessarily need to know what was causing the cycle.

You can just look at where on the horizon the sun rises/sets every day. On the first day of summer, the sun rises the furthest north in the northern hemisphere. So you just count the days until it rises that far in the north again.
Also, you can measure the highest point of the sun in the sky each day. If you have the same length stick or rock on the ground. On the first day of summer, at high noon, the shadow will be its shortest length of the whole year. So you can just count the days until the shadow is that short again.

It's not navigable this far anymore. Not since the Missouri River Dams were constructed in the mid 1900s.

Reply to Sock math (the case for buy it for life socks) by Johnpecan
Are 16 pairs of Darn Tough socks really going to last 8 years? I know they have a good warranty. But warranties tend to be a hassle and should have some cost associated with them for your time and effort. Plus, you probably lose a sock or few over 8 years which will prevent some of the warranty claims.
