Washing away a mountain?
« on: September 06, 2017, 06:44:03 AM »
Old timers were using hoses and pumps to errode away a mountain. Is that still now g done? What difference is between a 1.5 inch high pressure into a slice or aimed at a hill side?

Even a backpack forestry (censored)can makes a small sidehill water monitor that is good for localized use. Packing it when full helps you appreciate our hardworking firefighters, too.

Hi.Norbert.You refer to hydraulic mining.It is still done in certain areas.But is highly frowned upon.In the old days they did bring down entire hillsides and left a huge mess.In todays world that is not acceptical.Now if you are digging down a hillside and have a large holding pond,use your own discretion.Just saying.Luck,Mcbain.
I started out with nothing Istill have most of it.

You can bring down a hillside with an excavator, how do you put it back? There has to be leeway what is acceptable as far as restoring land.

How successful was hydraulic mining?

Look up old park videos in California.  They have some good ones on the hydraulic mining with big monitors. Miles downstream towns were flooded with mud from these things. The word is the recovery was about 2%..

One of the largest hydraulic mines is the Bullion Pit Mine near Likley BC. The wash valley is over 2 miles wide and a mile deep. The tailings all went into the Quesnell River and are resting in the Nitinat Fan.
