The respawns are kinda weird with Stone Golems. They seem to continuously show up around the old log cabins and stone wells you'll occasionally run into on the Mountains but sometimes it's a one-and-done. I'm curious if trapping them in a pit will prevent additional respawns? As for dealing with them, I do NOT recommend the pickax. It works... but can be troublesome if you miss. If you have end-game armor and weapons available, the Porcupine and Blackmetal shield are a great combo. A parry followed by a heavy attack with the Porcupine does a LOT of damage to them. I haven't tried the Iron Mace or Iron Sledge. Their attacks are easy to dodge and once you become familiar with the differences between the light and heavy attacks they shouldn't pose much of a problem. They're slow enough you can put them to use cutting down trees or breaking rocks for you.
If you're in the Mountains instead of running Sausages, Wolf Jerky and Boar Jerky, Maybe try Sausages, Cooked Wolf Meat and Eyescream? Eyescream is my favorite stamina food. Drakes are easy kills and you can farm a Greydwarf nest for all the Greydwarf Eyes (and resin, wood, stone!) you need.
