What a great find. Extremely informative. Especially for pet owners who may take unsuspecting wilderness walks. Thank you -Old former backpacker😊

Thank you for making this video. I recently went camping with my family and dogs at a state park in PA and they had signs posted warning visitors to make sure that your dogs didn’t drink out of the streams because of this bacteria. I didn’t realize how dangerous it was to people as well. Thanks again for all of the information and helpful tips!

We use a piece of copper pipe in all our stock tanks. It stops alga from growing.

Very informative and enlightening. I expect we'll see other brands create activated carbon add-ons. Is there one for the Sawyer Squeeze yet?

This was relevant for me, and well presented. So thank you.

6:59 Maybe not "dramatic" injection of nutrients, but what about from backcountry campers and their catholes? That lake basin is a catchment for all the hikers that travel through there. Yosemite backpackers, PCT'ers or otherwise... anyone in the last 100 years or so who wanted to climb a mountain and decided to poop on it. I appreciate your practical solutions and overall discussion on this topic.

Very curious about the impact of human waste in the back country on cyanobacteria, but that part of the Sierra has active cattle and sheep grazing leases that have been grandfathered in for generations. With herds in the thousands going through in the warm months, it's hard to imagine human waste having a comparable impact. It should be noted that the basin he singled out is on the Hoover and Inyo side of the crest divide and would not be a catchment for PCT or Yosemite hiker waste.

Very good discussion, learned a bunch from this!

I saw cyano mats in upper Rae Lake a couple of years ago and I was pretty surprised (and saddened) - further evidence of human impacts on wilderness areas.

What about boiling?

Great info! Thx.

Does anyone here know if the cyanotoxin is heat-labile?

@billb5732 18 дней назад

Nice PSA, thank you. Charcoal is readily available to backpackers -- can be made in minutes almost anywhere below tree line. How much do I need to eat for first aid? Are there any quality guidelines?

@kensmith7567 19 дней назад

Question related to filtering and then passing through a carbon filter. If the filter media captures the bacteria does that mean that the bacteria will then die in the filter and release the toxins at a later date?

@keelanrose5706 18 дней назад

backflushing will take care of that. it should get rid of nearly all the algea and if there are dead algae it'll get rid of the water soluble toxins. After using your filter for a trip you should soack it in clorine dioxide water for a few minutes to kill off any algea and bacteria (not just cyano bacteria, also any others). Then backflush and you'll have a nice clean filter. also use vinegar if you think there might be some mineral build up from filtering hard water.

And what about the east coast?
