i found a non barrel thief cache

[LucarioNinja]

go outside ysloda's house in whiterun, facing her door. on the right
side, the wall there has a thief cache mark and there's a tiny chest.
never been to riften, level 22. is this normal, and are there other non-barrel,
non-thieves guild thief caches like these

Huh i never noticed that one before.
It is there like you said.

I can confirm that it is there on a completely vanilla game.

Very interesting! Even after over 5000 hours this game still surprises me. It looks like it's not on the UESP wiki page for thief caches either. Funny how I never noticed it; I think with all my mods like grass and city overhauls it must have been even more well hidden.

Thanks for sharing, you made my day!

The odd thing about this is thieves would never alert other thieves to a cache. Ah well, thats what I get for thinking.

Ive never noticed it either.

There's another non-barrel thieves cache in Irkngthand Slave Pens in between two potion bottles. At a certain point you can get up to Dwemer pipes. At the end of the pipes you can find the cache shadow mark. It's above a Falmer hut, a Falmer shaman, a chaurus and a campfire.
