Mini-Squeeze Sawyer filtration review

Anyone who's hiked with me knows I've been toying with the idea of building a lightweight gravity filter system for 5 years. The problem up and to this point was finding a filter that didn't require a heavy pump system, wasn't bulky, could be integrated into my current water management system, and was less than 3oz wet in order for me to consider giving up my fast and light system of drop and go multi-bottle purification.

The newly released 2oz inline Sawyer Mini-Squeeze kit fit the bill. (released ~October, 2013) is a lot less bulky than the previous Sawyer Squeeze. I still retain my 2 bottle system, allowing me to add a chlorine-dioxide purification treatment when needed in conjunction with filtration. On long distance hikes, the compact size will actually fit in my compact 9oz frameless pack.  Carrying a 8 to 14oz pump was not likely to ever happen. The benefit of this system for me was that I was retaining both 1L primary bladders, and it screwed onto my current platypus setup with no modification or added hoses were necessary. Reducing any added weight, complexity, or forcing me to switch away from my collapsible water carrying system.
Filter with supplied 16oz dirty bag.
Filter paired down for carrying

Measured Weights:
Filter dry weight:                 1.35oz
Filter wet weight:                 2.00oz
(shaken out)
60mL Back flush Syringe:    1.20oz
(supplied)
20mL Back flush Syringe:   0.5oz
16oz dirty bag:                     0.8oz
1L platypus dirty bag:         0.9oz
(already carried)
Stuff Sack:                           0.25oz

Operation:
The function of this system is basically fill the dirty bag, screw the filter on, and squeeze the water into the clean bladder. Flow rate with a clean filter was excellent. The dirty bladder can still be used to carry water for dry sections of trail where carrying water is necessary. The system comes with a measly 16oz dirty bag, that can be swapped out for one of the 1L bladders you are already carrying. With a 1L dirty bladder, I was getting just a little over 0.9L of return water. A little is left in the bag, and in the filter after filtering.

Parts laid out, ready to be attached.

Filtering in progress.

Backflush:
The operation of the back flush/field servicing is one of the simplest I've seen while kicking around filters. A 60mL syringe is included that you fill with clean water, push up against the clean end, and press water through the filter in reverse flow. After using the filter for filtering 2 people's water last weekend's trip, with no slowing of the flow rate while using fairly clean mountain water... I'll likely leave the back flush system at home, unless I'm going on a long trip, or somewhere where I'll likely have to filter seriously dirty water (not as common in the NW). I'd also toy with the idea of carrying an emergency 20mL syringe to reduce the weight carried, and reduce the bulk of the 60mL syringe.
Basic back flush setup. The Syringe is bigger than the filter.

Supplies:
Included supplies are a 16oz dirty bag, 0.1 micron filter, straw, and 60mL backflush syringe. I added a small mesh stuff sack to hold the dirty bag, filter, and backflush syringe. As you see I also increased the size of the dirty bag.


Other possible options:
Frontier Pro Pre-filter mod, to help from clogging the filter when using dirty water. There's an excellent write up if you search the internet, and you will have to break off the nipple on the dirty side to screw it in.

Gray Wolf River, (Slab Camp to Camp Ellis)

Another round of early season backpacking in the Olympic National Park. This trip was to another river valley that I had never been to, the Gray Wolf River. It was also an introduction to backpacking for my best friend Lyss! Apparently reaching the upper stretch of the Gray Wolf River Valley into the ONP requires taking a side trail down hill on the Slab Camp Creek trail due to a trail bridge washout on the lower reach of the trail. You can also more readily access the upper stretch in the ONP by Deer Park rd if it was open, but that road is not currently open and you'd be taking the Deer Park access trail from the same parking lot anyhow. I wanted to see the valley!

After a late start, nearly noon by the time we set foot on the trail, we scurried down hill to Slab Camp on the Gray Wolf river via a well maintained National Forest trail through the Buckhorn Wilderness. You start out in the 2500' elevation range, and plummet downhill to the Slab Camp in the 1500' elevation range. The downhill start is a little inverse for a river hike. In that you lose so much elevation before even starting to climb the valley, which is unlike most ONP river hikes.

After crossing the large bridge across the river you make up for the loss in elevation fairly soon. The trail pulls away from the river and climbs on a narrower path high above the river. The path is laden with moss, and an eerie feel of the recovering forest from an old burn. Small trees strewn across the hillside's floor. With glimpses of burnt stumps, hollow trees, and scorched sections of the few surviving older growth trees in this area. The narrow path meanders along steep forested hill with the occasional trail engineering to maintain a walkable path. As you approach Slide Creek camp the forest thins a bit, and crosses an open rock scree field that gives you glimpses up into the valley. By this point we had passed both large groups, and accounted for all of the cars in the parking lot. After Slide Creek we had the rest of the valley in isolation for a very peaceful, and silent wilderness experience. Rarely is it with this much solitude.

Slide Camp was the first test of the new 2oz in line sawyer mini-squeeze kit. I'll have a further review of use later, including maintenance, and function, but in essence I still retain my 2 bottle system allowing me to add a chlorine-dioxide purification treatment when needed or on light and fast hikes. It also has a no-frills, no extra parts required and was fully integrable with my platypus bladder systems that I currently use. The release of this filter in October of 2013, is likely going to change my water system permanently. The old Squeeze was too bulky, and heavy... The new mini-squeeze is trimmed down and won't be as bulky in my space is limited 9oz frameless pack when I choose to carry it.

After Slide Camp you go up, down, cross another fork of Slide Creek and then you cross the ONP boundry  where shortly after dogs are no longer permitted. We found a wider spot and sat down to make Chicken Ranch wraps and snack on some bacon before we began the slow descent to the Gray Wolf River Camp where the backcountry self register box still exists. I'm not sure if anyone is picking up permits. Having already registered at the Port Angeles WIC we took a left and headed up the river valley. Until this point, other than crossing the Gray Wolf River at Slab Camp we were high above the river and out of sight of the river below. Starting at Gray Wolf camp you are following right along the river for the rest of the trip up the valley. Around this area the forest slowly begins to become older growth as you go further up the valley. Along the way there was a long log crossing, and more meandering through majestic mossy woodlands until we reached Camp Ellis. We decided to stop here instead of pushing on to Falls Camp after such a late start. Setting up camp, overfilling our dinner with water, and making some tent maintenance required before the next trip we finally sat down to make a fire and relax before crashing for the night.

The next morning we made an amazing breakfast! (which Dani and Richard introduced to me on the last backpacking trip). 2 quart ziplocs were filled with a half packet of Idaho instant butter mashed potatoes, and half a packet of McCormick peppered gravy. A third bag was filled with a 1/2 cup of Providence Pantry freeze dried sausage crumbles (boy are these tasty! even without re-hydrating!). The sausage was re-hydrated with the requisite amount of water, and we found that between 1-1/2 to 1-3/4 cups of hot water was about right for the FBC method. A side of Oberto Applewood Bacon Jerky made for an amazingly filling and delicious backcountry breakfast! This will likely be a staple from now on.

After breakfast we finished tearing down camp and meandered on to Gray Wolf camp. We crossed the Gray Wolf River and had a snack alongside the larger tributary of Cameron Creek. From here it was up and on out. At Slab Camp we stopped for an Italian Sausage, Baby Bell cheese, spicy mustard and mayo wraps before the haul back up the hill to the car. Up and to this point we had barely encountered rain showers, and at lunch it was blue skies and sunny! On the up hill out of the valley, this slowly changed... The closer we got to the ridge, the larger the drops of rain!

Gear in review:
The new filtration system is going to stick around for at least a few more trial runs if not indefinitely.

The adjustment to my rain gear on this trip was adding the rain wrap back into the equation like mentioned in the recent Elkhorn trip. Using that in conjunction with converting my pants to shorts kept me significantly drier. When I get the sewing machine back, I'll fabricate some sil-nylon trail gators for those trips of imminent rain. Knowing my shoe's gore-tex is shot I'll need to test the current rain system with non-leaky shoes anyhow.

The Ti-SOL Jetboil is still kicking strong. It is usable for 2, with at least 2 boils of water for breakfast and drinks. This trip was an experiment, to see how much of a hassle it was and whether I wanted to take one of my larger 1.3L or 2L pots with next time.

66" Neoair pad, Neoair sit pad, and my down jacket in an 8L Ultra-sil dry bag for a pillow is definitely the most comfortable sleep I have been in the backcountry! This setup is staying...

The Shipwreck Coast and Hurricane Ridge Olympic National Park

Well, the initial plan was a 3 day 20.1 mile hike from Rialto Beach to Ozette, but I had too much to do to get the pickup ready to tow the Subaru to the ending point. Not to mention not enough money to get it done in time for the trip. So the trip was restructured to about 17 miles, Rialto Beach to Cedar Creek, but just over half way to Cedar Creek Heather's shin splints were acting up from climbing over all the rocks. At Cape Johnson we decided to turn back to the Chilean Memorial and just setup camp. At Cape Johnson and shortly pass it there is 2 points that have to be crossed before the tide gets too high and we were 1 to 2 hour from that high tide. Hast would of had to have been made and with Heather's shin splints it was decided that it would be best to just make camp at the Chilean Memorial and not create a death march for Heather. I really enjoy her company and don't want to wreck any future chance of her backpacking with me. So in total, the trip was 9 miles from Rialto Beach to Cape Johnson.

Day 1, After taking my chemistry quiz, we did the inevitable forgetful dance of leaving small things at the house and coming back before we finally escaped the clutches of the house. The extra hour of driving on Hwy 101, behind all the slow people that can't read the speed limit signs was brutal... After finally picking up our camping permit and bear canister from Port Angeles WIC we headed to the store for some food and other odds and ends. A few hours later we finally made it to Rialto Beach around 7ish on the trail by about 7:30ish. We hiked out roughly 1.3 miles just shy of Hole in the Wall and found a camp spot tucked away in the brush above the tide. Magically a softball appeared at the entrance of our camp after the tent was setup... Any ways we finished setting up camp and hoped to catch a sunset which wound up being fairly drab. Then off to bed for the night.

Day 2,
We hiked from near Hole in the Rock to Cape Johnson and then back to the Chilean Memorial to setup camp and hang out for the day. This is the most down time I've had on a backpacking trip... At the Chilean Memorial we also got around to cooking some raspberry and strawberry oatmeal mixes, mmm... dehydrated berries and oatmeal! Than we played a few games of war, and collected some water. Found out that the activator for my Aquamira was a 1/4 full and the chlorine only had enough for one liter. Thankfully I carried in twice as much water as I normally carry. Lesson learned check both bottles for how full they are versus just one even though they are a 50/50 mix to purify, or as what I'm headed to REI for today... Micropur ClO2 tablets so that I can just carry what I'll need plus a few more. We had to use Dead Man anchors for all but 3 stake points on the myog tarptent. The stakes just didn't want to hold in the soft sand, but logs did :D .

Day 3,
Packed up and headed out for the car. Heather opted out of a breakfast stop along the way and we hiked through to the car and off to Forks for breakfast. Than off to the WIC in Port Angeles and we took a side venture to Hurricane Ridge.

A little reflection here instead of another post... The pie tin windscreen will still be a temporary recyclable piece of gear and I'll just remake it as needed. It holds it's shape really well compared to the old aluminum foil one I had made previously, but some of the strong winds blew the flame enough to melt a little aluminum away near the burner head on one side. When I buy some .016 Ti sheeting to make a Mont-bell style trowel I'll probably just make a base out of that for a more permanent solution one day, for now I have 2 more pie tins and plenty of trips left on the current pie pan base.

As for the Tarptent, the permanent floor was a great modification, but I found one more thing to modify. I'll be putting elastic attachment points just like the corners halfway down the long side of the tarptent to keep the floor from migrating inwards as you move on the pad and reducing the center width of the floor. Other than that the tarptent worked great!

Also always check both bottles of your Aquamira for how full they are, or switch to Micropur tablets which are a higher concentrations of ClO2 and have a full EPA purification certification without doubling or tripling the amount of Aquamira you put in...
