Chapter 2 / 3: How do the tribes cross the rivers?

[markrivett]

I'm studying this adventure path, and I haven't found any reference to how The Broken Tusks (and the Burning Mammoths) cross the river to Gleaming Sun Lake then the other river of their way to Red Cat Cave?

Do most GMs just assume that, being that the tribes are extremely familiar with the terrain, know how to ford a river?

I don't see where the adventure path address a couple points that I, as the GM, may be overthinking?:

I thought the setting just came out of winter and is now in spring. Normally this would mean rivers are taking in all the melted water and are high, fast, rough, etc.

There are at least 3 newborn babies traveling across these rivers.

Is this something I don't really don't need to/shouldn't need to be concerned with?

If there isn't any reference to crossing these rivers in the adventure path, is it a good idea/bad idea/neither good nor bad idea to homebrew some increased drama around these crossings?

Thank you in advance.

I assumed that there's no way the Broken Tusks (or any following in the realm) don't have experience fording rivers. I didn't personally add specific drama to this, though if you're really leaning into the complexities of the terrain and exploration, I think that could be a lot of fun.

One obvious mediating factor for me was that the Tusks have access to several mammoths - I could easily see a world where Argakoa lets her daughter and grandbabies ride with her over the difficult parts!
