    There is no way to wrap anything around the rock that is stuck. It is wedged in such a way that the force of the rock was pushed and is practically seamless with the bedrock on each side. Obviously I can see there the two rocks meet and touch but I cannot get any tools in between. I need to crack the edges / center somehow. Ill look into the Sierra Blaster but a come along and strap arent going to do it unfortunately.

    If you cable pull it be sure to drape blankets over your cable (in the air) it will make it so if the cable snaps it won't whip lash back to you...a very dangerous situation! We use a "geared" big hand boat crank and have chains and a webbed boulder draped puller.

    On page 34 of Advanced Dredging Techniques volume 2 it describes opening a boulder bound hole, tight packed rocked that cannot be grabbed by a sling. It talks of using a slide hammer to drill a hole to attach a modified eye bolt. An A frame hoist is used to yank the rock up and out.

    Two of these - https://www.harborfreight.com/6000-l...rap-61226.html

    1 around an anchor(such as a suitable tree), the other around the boulder(if you can get around it), other wise search for something similar to this https://www.rescueresponse.com/shop/cmc-1-flat-webbing/

    And one of these bad boys.

    You'd rather have you're straps fail before your pulley!



    Edit - Sorry Honkey.. I can't read apparently

    I would recommend synthetic winch cable. It is just as strong as steel, does not stretch with load and is much lighter making it much safer if it breaks under load.

    If possible I would stay away from synthetic winch cable in typical mining operations. It is very fragile if not handled with care. It is very susceptible to abrasion and does not like have grit in the fibers. Maybe for one pull but the the cost of the synthetic may not justify it. If you are in an extreme remote area then maybe but your call. Steel sucks to carry but the cost, and the fact you'll only buy it once has once, has its advantages.

    YMMV

    Now I need to decide whether or not to get a thicker wetsuit and full face mask and attack it now while the water is relatively low or wait for summer..... Ive been thinking about this damn rock since October

    3k how fast is the water? The faster the water the more "I" would stay away from the full mask. It's a lot easier if you loose your face gear to clear just a regulator to get a breath and then worry about getting mask back on. With a full mask you might not have enough air to clear the whole thing just to get air

    Not sure of exact temperature but this time of year it is cold enough to sting - it is very painful after a minute or so in the water. This time of year I have to pan with neoprene gloves or forget about it!

    That's everywhere in the Sierras. Last year in July I couldn't grip the tab on my fly to drop trou to pee. Almost got ugly.

    I would second the suggestion for using the Sierra Blaster. You can break a rock that size with one charge from a micro blaster.

    Depending on how deep the stream is, you could also drill some 5/8" with the drill located on the surface, using a long drill bit. Then you can either feathers and wedges.

    You can also get a Tirfor winch and haul it out by hand in one piece if it's really that big and not stuck in the sand.

    The Fish and Wildlife folks will eat you alive for blasting in a waterway. The concussion, shock wave, and sound is conducted efficiently through a dense medium, such as water. The upside, fish for lunch or dinner.
    Don't

    First of all the Fish and Game folks will eat you alive. An act like that will definitely give the tree huggers more ammo to shoot at us. The upside is wholesome nutrition... fresh fish for lunch or dinner. I personally would use a cheap electric winch from Harbor Freight, some chain to anchor to a tree or whatever, and winch the boulder out of the way.

    The blasting idea leaves you some simple choices... six men to bear your coffin or twelve men/women to act as a jury.
    Don't
