I'm not a trail dumber-downer - just thinking the SIUE description on the site may need a little updating and possibly be rated as beginner/intermediate.
We used to buzz that on CX bikes at night no problem. Even pulled my son (now 20) on a trail-a-bike over every part with no real issues.
I know I'm old but last night I rode it on my hard tail instead of dually and it isn't the same trail as it used to be (for better/worse) - way more rooty with some gnarly up/down root balls to clear and some armored crossings (big one on trail 4 near trail 3 is a fork snapper/face plant if you hit it wrong)
Only mentioning since I happened to notice the rating when putting in a conditions update and I ride Cliff Cave a lot which is beginner/intermediate. Other than the short rock garden, Cliff Cave is a smooth superhighway by comparison imho.
Not suggesting the trail get changed although I'd be down for helping re-work some crossings that are shifting/sinking
