Six Moon Designs Lunar Solo 2011 tarp tent

This tent has two versions defined by support pole length.  The instructions for my 2011 tent indicate a 45-47" pole.  Newer years take a 49" pole.  I have used 49" with mine with no adverse results.  No matter the length of the pole, ventilation under calm conditions improves with a little elevation of the side and rear guy loops.

I used this shelter in my 10 night 2012 Wonderland trek, a 2013 High Divide 3 night trek, a two night camp at Gem Lake (above Alpental ski resort and past Snow Lake) and a two night Home Sweet Home camp out.

Video above shows set up process

Pros:
  • Quick set-up, six stakes minimum.  It has additional pull-outs, but no lines, on each end of the tent to increase head room for the sleeping camper.
  • Single pole
  • Generous 26 sq ft of floor space, mostly usable, but not for a second person.  It's still really a one person tent.
  • Generous vestibule that fits pack, boots and allows entry/exit.  Even though I'm a fair weather camper, I can see that it would provide enough room to cook in rainy conditions.
  • Bug protection
  • In conditions where rain falls straight down or from the back side of the tent, the vestibule can stay open for ventilation.  I have used it that way in Fall 2013.
  • The zipper works well, but the too-short pull tabs have no zipper pulls.
  • flexible set-up for weather.  
  • My 5'8.5" frame fit inside lying down with some space beyond my sleeping bag clad feet and head.
  • 24 ounce weight.
  • I have enough head room to sit under the peak.


Cons:
  • The side and rear stake out lines on mine have thin Grosgrain (the "s" is silent) webbing and ladder buckles which hold, but they neglected to sew a fold on the end of the Grosgrain to keep you from pulling it off.
  • Fiddly but effective vestibule tie-up (elastic cord "buttonhole" and plastic bullet button)
  • The tent allows you to adjust only the front line while in the tent.
  • The siliconized nylon canopy stretches after set up, requiring cinch, which you can't do from inside because of the bug netting.  Adding zippers might add 3 ounces.
  • The siliconized nylon floor requires some preparation of the floor to reduce slipping around.
  • You'll want either a tyvek or poly cro (shrink-to-fit window film) ground cloth as some people hint that the floor isn't completely waterproof.
  • You can enter/exit only from the right side of the supporting pole.
  • Without the optional side pull loops staked out, you'll have the canopy almost on your face while lying down, especially if you sleep on a lofty air mattress.  That would also tend to worsen condensation.  You'll need a stake and about 6' of line to raise the canopy on whichever end you choose as the head end of the tent. Another stake and 6' of line will keep the canopy off the foot end of your sleeping bag as you sleep.
  • Likely a tight fit if you're over 5'11"

Those people in the pool

Who are those Asian women in the Desert Breeze swimming pool?  They are all 52 years old, wear a latex cap with chin strap, float or swim laps as if they measured their minutes in geologic time, speak to each other in hushed tones and have much more than 99.9% of their DNA in common.

While walking to the pool from the locker room, and before I could even see the water,  I heard a man barking commands as if he were coaching a swim team of a thousand.   A fit middle aged man on the pool deck directed elderly women in a water aerobics class.  Life happens at the Desert Breeze Aquatic Center.


No money to save the Enchanted Valley Chalet

in this world nothing can be said to be certain, except death and taxes.  ---Ben Franklin 

I've been there and sat on the splintered wood porch on a sunny, warm September day.  The Park Service reserved the building for ranger use and for dire emergencies.  I imagine people would pay a fee to stay there, though the cost of maintaining a shelter with four walls, doors and windows could exceed revenues.

Saving it?  The Park Service has no $ for this one.  History, sure, but at what cost?  The wilderness will reclaim its own.  Let our $ go to maintaining trails and protecting wild lands.

yet another Wood-burning stove


I hate these things.  I cannot stop making them.  I hate the soot that collects on the two saucepans I sacrificed to wood stoves.  And most likely, the controlling authority where you'll be camping won't let you use these.

Concept:  The gasifying wood burning stove to my knowledge has two parts.  The firebox has air holes at the top and the bottom.  The heat shield is a box that surrounds that fire box.  The heat shield has vents at the bottom to let air into the fire box (primary air source) and up into the space between the fire box and the shield (secondary air source).  The picture below from Wikipedia shows how wood gas from partial combustion flows down from the fire and back up between the fire box and the heat shield with secondary air as both warm up and rise between the fire box and the heat shield, moving back into the fire box when it reaches the top.  "most of the carbon monoxide produced by gasification is oxidized to carbon dioxide in the secondary combustion cycle."  That's the theory.



Instructions on how to build wood gas stoves (some very elegant) abound on the internet.  The variant I developed and show here allows modifications after construction, such as adding more air supply holes.  Of course, it is so cheap to build that one can simply build more.  It consists of two cans which one can find easily in US supermarkets.

Stove construction
Materials:

  • Steel tomato can (4" diameter) for heat shield: 104 gm
  • Aluminum roof flashing 4.5" x 13.75" to replace tomato can side panels
  • Pineapple can for  burn chamber (3.5" diameter) with top off:  75 gm
  • 2.5" x 12" hardware cloth for pot support
  • 3.5" square of hardware cloth for raised floor
Tools:
  • Can opener
  • Rotary tool (Dremel or Black'n'Decker RTX for budget minded folk) with cut off wheels for cutting cans
  • Heavy duty scissors
  • drill and bits
  • rivet tool and rivets
  • ruler
  • gloves, ear plugs and protective eye wear when using tools
Process 
  1. Heat shield:  remove top of the tomato can and cook/eat contents.  weight= 91 gm
  2. remove label  wt=88 gm
  3. Turn the can so the bottom is now the top.  Cut out a 2"circle from the top.  wt=82 gm
  4. remove 4 panels from side of can leaving 4 struts (non load-bearing)   wt= 45 gm   (If I do this again, I'll remove two panels & delete step 6)
  5. Place Aluminum roof flashing inside the shield and mark four spots at 3, 6, 9 and 12 o'clock.  Cut out air holes at these four spots with the rotary tool.  Attach flashing to inside of can with a rivet at the bottom of the can.  This will bear the weight of the pot support and the pot with at least a liter of water.  Shield wt= 74 gm
  6. remove two struts Shield wt= 67 gm  
  7. Make fifteen to twenty 1/2" radial cuts from the 2" circle, forming 15-20 tabs
    Heat shield with radial cuts on the top.
  8. Bend down every second or third "tab" & remove the other tabs.  Heat shield wt= 67 gm
  9. Cut away the last two struts and the bottom ring of the original tomato can dropping another 11 gm.  final weight 56 gm.
    Heat shield with tabs bent down and side panels removed
  10. Burn chamber (burn box):  remove label from pineapple can wt= 71 gm
  11. Leave the bottom of the can intact.  It will serve as a heat shield to help protect the surface on which you use the stove.  Flammables will still 
  12. Make marks at 3, 6, 9 and 12 o'clock near the bottom of the can.  Draw a horizontal line about 3/4" long at each mark 1/2" above the bottom. The raised floor will rest at this line.  With the Dremel cut four "U"s at the bottom to create tabs to hold the raised floor 1/2" above bottom, bend tabs up.  Now cut upside down "U"s at the same marks to create tabs that you can bend down.  These should be about 3/4" high and narrower than the tabs that we bent up.   
  13. cut hardware cloth to go inside can as raised floor 
  14. place floor in can on the tabs we bent up in step 11 and bend tabs down to hold the floor.  Burn box wt= 74 gm
  15. Pot support:  shape Hardware cloth to fit on top during use and inside the tomato can for transport.  Don't try to cut this pot support so that it's smooth where your saucepan will rest on it, because soot will make the more likely to stick to the pan.
  16. I think you're done.  Pot support wt= 15 gm
Total weight 145 gm (5.1 oz), a bit heavy compared to a stove with just the burn box and a simple heavy duty foil heat shield. I suggest you make the burn box with the tomato can and get heavy duty foil for the heat shield.  Just keep it simple.

Storage:  the pot support goes inside the Heat shield and the burn box goes inside that.  It's a bloody tight fit.

Use guidelines:
Place the burn chamber right side up.  remove the pot support from inside the heat shield.  Place the heat shield over the burn box, such that it is centered--the tabs in step 7 may just reach inside the burn box to help with that.  The Heat shield is taller than the burn box.  The gap between the tops of the two cans allows the warmed air between the two cans to move into the space over the burn box and mix with the rest of the burned gases over the fire, supposedly to help burn the wood gases more completely.

Swim blog: butta'fly

One cannot photograph or otherwise record a feeling that one can re-experience on playback.  I have been feeding myself Tylenol, naprosyn and Glucosamine/chondroitin for a few weeks now.  That in combination with some physical therapy stretches and strengthening moves have reduced my right shoulder discomfort to where I can commit myself to paddling a good Ski to Sea 2014 race.

The shotgun combo of drugs seemed to help with swimming.  I hiked from noon to 2 p.m. with some big hills, came home and napped for three hours.  I got to the pool by 5:30, swam a few laps of freestyle and breast stroke sandwiching some kicking laps.  I swam a few dolphin kick laps and noticed a feeling that my calf wanted to cramp, which brought me to swim a few dolphin kick laps focusing on just the hip flexion and extension phase, ignoring everything below the knees beyond keeping my feet together.  I swam one armed fly, breaking into full stroke by mid length, still focusing on hip flexion as well as timing the hand release with hip flexion.  The stroke felt fluid and the energy seemed directed toward forward progress with little vertical motion.  I could even swim 50 yards of fly without the usual exhaustion.  This had to have been an unrepeatable fluke, but I loved the feeling even knowing that I cannot press "Replay."
