Slide layout is OK. The second A1 (26-34") would be an A3. Bts isn't an allowed combination by USDA Soil Survey Manual dictates. C & Bts is not a possibility. You describe all horizons as gravelly or very gravelly. That woud strongly suggest that this is fill material to mitigate for wetness when your property was developed. What do you think? If true, you horizons would be ^Ap, ^C1, ^C2, etc. (human-transported material.

See my comments on previous slide. Also, eliminate structure description which can't be made with an auger excavation. Regarding structure, "massive" is always structureless never weak, moderate or strong. By saying massive your saying there is no soil structure.

2 (02) comes before 4 (04) and you began presenting site 02 information before site 04. I suggest maintaing that logical sequence rather than switching to putting site 04 first. The more logical and consistent the sequence the easier it is for the audience to follow.

"Carbon content" and especially "oxygen content" aren't usual description items. Why do you describe the light-gray E horizon as having moderate carbon content, the same designation you gave for the Ap1? I would wager that the Ap1 has much more organic matter than the E. I suggest removing carbon and oxygen content references. Also, humic substances can't be judged from soil color alone. Your Bh2a would be a Bh2 and your Bh2b would be a Bh3.

Good slide. I increased the font size a little. Why do you give slight limitation for septic tank absorption fields?
