Small retaining wall question

I recently dug a path down to the river at our house. I'm trying to figure out the best way and the cheapest way to hold the dirt back on each Side. It's about 28 feet long and 2 foot high on each side. I was thinking of just doing a wood type retaining wall. Just drive treated 2x4 about 2 feet deep and screw deck boards between the stakes and the dirt.

OK, let's start with why did you have to dig in the first place? And then what's the composition of the soil? And then how long do you expect/require this to last?

Most 2"x treated lumber is NOT treated for ground contact and it won't last very long. You would need to step up to doing everything out of 4" or 6"x material to get wood treated for ground contact. Or, you can special order 2"x lumber that is specially treated for ground contact but it's harder to find the further you live from the coast.

It was a steep hill to the water and we want to be able to haul kayaks and canoe down to it. The soil is fairly loose.

Menards in Ohio has 2x12 rated rated ground contact. Should I dig more out and go with stone then? If I do that I was thinking of getting a load of 6 to 10 inch rock and putting a layer on each side
