Deep hoofprints in frozen mud
I hope this is the right place to post this question.
I'm actually a boarder, but I've got a maintenance issue.
Yesterday was warm enough for the mud to melt, and despite my instructions not to turn my (recovering from an injury) horse out if it's muddy, the b.o. let her out in a very deeply muddy paddock. Today it all froze back up again, so now there are deep (6-8") post-hole style hoofprints frozen in the mud. Today I came out to find my horse out there, wobbling through this chop, unsteady on her feet and struggling not to get stuck in the holes -- yikes!
The b.o. claims it's safe because they go carefully through this footing, but I know that if something spooks her she won't be so ginger about it. Plus, the worst of it is by the gate and in the areas she likes to spend time in, so it's not something she can/will just avoid. I'm not happy, but I'm not able to jump ship on this boarding situation right now.
If she is to go out at all in the next weeks/months I need to make the footing safe. I don't have heavy equipment (nor would the b.o. let me bring any onto the property), but the b.o. would be amenable to adding or moving around material manually, as long as I don't change the consistency of the footing too much (e.g. he wouldn't want something like gravel).
Is there anything that can be done to make this safe? Do you think it would work to tamp soil or sand into the holes? Could I manually pound down the unevenness with some tool like a sledgehammer or would that be insane to attempt?
Today I spent a stupid amount of time trying to relocate whatever clumps and clods I could pry up into the deep holes, but that was a pretty feeble attempt at improving it.
Any advice is greatly appreciated!
