It looks like SE or possibly USE.
In any event, it is required to be protected from damage.

Jeff, the cable was just strung out under the crawlspace…This is near a marsh so theres always a lot of moisture if not standing water under these houses.

Through the crawl space it would be required to be properly secured (much like you would expect to see NM/Romex secured).
Where it exits the crawl, it should be protected by conduit and/or burial.
The type of cable is important to know. It must be listed for "wet locations" if it is buried.

I can see in the photo that there is printing on the jacket. If you could find a place where it is legible (such as back in the crawlspace), you would find out what type of cable it really is. If it is SE, SER, or UF, then it would be suitable for wet locations. If it is NM or NM-B, then it is OK in the crawl space, but not outside in a wet location.
However, once a cable exits the house, it is no longer allowed as a wiring method for a spa or hot tub. Also, if that cable is aluminum, it is not allowed because the required equipment grounding conductor must be copper (and it must be insulated).
Permitted wiring methods outdoors for a spa are rigid metal conduit, intermediate metal conduit, rigid non-metallic conduit, Type MC cable listed for the location, and where a flexible connection is necessary, liquidtight flexible metal or nonmetallic conduit.

Aaron,
No reason why not, the sections you cited do allow for cord & plug connections & this would be much easier than installing the required wiring methods in many cases. I've got to admit though, that I have never seen a spa that requires a 50 amp circuit that was plugged in. Maybe no one could find a bubble cover for the receptacle

I tried to look closely but the amount of dirt that had collected mad the writing not legible… Thanks Jeff…

No matter what is on the sheath of the cable 400.8 forbids the cable to come from the inside to the outside.
The rules are found in part two of 680

| This cable ran from the sub panel to an outside spa, |
If the cord came with the tub then I see nothing wrong with it lying on the ground as it would be expected to do so as outlined in 680.42 for the cord and plug connect outside tub as long as the receptacle is on the outside.
