Fixing a hammock to rock

[TLM]

Has anyone experience to fixing one/both ends of a hammock to rock (cracks I assume ...). I have no experience in climbing so what kind of hardware is available and what works?

I have noticed that finding two trees at proper distance is not always easy but at times a cliff face and a tree seem to be right there and in certain areas one can find a lot of cliff faces. Especially in Lapland trees at times are not very cooperative.

This ^^^^^^^^
Have a look at some jams and clogs (chock stones.).

@nigelp Beat me to it!!!




Edited to add:
It is possible to do the same thing with a wire or textile loop placed around a natural stone that jams into a crack. A loop from your hammock could work if the cleft lines up ok.

Be careful. These things only work in one direction of pull.

Only thing I have seen is a portaledge, the climbing beds you attach to a rock face. Carrying the hardwear you need to anchor into rock seems like you'd be better off just taking a hammock stand!

I’ve not done this with a hammock but have wondered the same thing, esp near beaches in this part of world. Have experimented with home made climbing nuts holding up a tarp, seemed to work.
I’m not a climber by any means but it seemed an interesting possibility, and an interesting history.

History Of Climbing Nuts - Peak Mountaineering - Protection History

The rich history of climbing is reflected in the range of equipment that has evolved over time. Our history of climbing nuts is one example.

There are folks who hang of the sides of mountains to sleep in multi day climbs, and while I doubt their sanity, the possibility for a hammock 12 inches off the ground seems obvious.

I’ve used them to hammock on Dartmoor many years ago. It was a novelty pitch and planned in advance. I recall we only took 4 ‘nuts’ each and used climbing slings also.

Cams would work as well

OK, it looks like these devices come in a palette of sizes, both the nuts and cams; now what device would cover the largest range of crag sizes and as somebody noted I probably do not need all the load capacity a climber would. looks like as a rough approximation I would need about twice the total weight carried, that would give a "safety" factor of 2. Of course if the ground is rocky more would be very desirable.

Clog size is very little to do with load capacity. The smallest one will probably hold you easily.
The size of the clog is to fit the variously available clefts. They are all designed to do the same job: to catch a falling climber (with luck).

A cam will fit a wider range of crevices but perhaps not so much the smaller ones. No one can advise you without seeing the pitch.

The rock has to be right too. Shales and schist won’t hold anything. Oolitic limestone can be hard to grip.

I’m not a hammock user but given the limited exposure of your bum in this case, I’d certainly give it a go. I might have a sleeping mat with me for the first few goes in case I had a sudden change of sleeping altitude in the night.

Shales and trees kind of reject each other here, I guess at about 90% one would meet granite and gneiss, calcium carbonate rocks are very rare, as far as I know always marble.

For variability probably cams tbh
