Obviously there is a lot to say here, but first the first thing that would help is knowing more about the temperatures and conditions you expect to encounter, but I’ll go ahead and give a few suggestions anyways.
Ax – really, an ax, unless you are a firefighter or trail maintainer, there is no reason to carry an ax in the backcountry, no matter how small it is.
50ft nylon rope – perhaps it is just worded rope and this is lightweight cord for bear bagging, but I have seen way too many people carry rope in the backcountry for no reason at all.
REI Monarch Boots – once you go to trailrunners you will never go back
OR Rocky Mt High Gaiters- this obviously isn’t a snow list, so these are way overkill. If you must have gaiters, look at the Integral Designs eVent Shorty Gaiters.
5 liters of water storage? If you like hydration bladder, platypus bladders are a lot lighter than camelback. I would think in Minnesota, you could get by with 2 liters.
REI First Aid Kit – this has to be heavy, make your own kit for 2oz.
Plastic Trowel – You could probably just use your heel or trekking pole
Leatherman Blast – 6.9oz! You can easily have more knife than you need for under 1oz. I like the Spyderco Ladybug.
Carbiners – You probably don’t need these, I don’t carry any anymore even for bear bagging, and haven’t missed a thing.
REI Double Wall Ti Mug – Ditch this and drink out of your pot
.9L SS Pot – Try a Ti pot and a smaller .6L volume for solo use.
Candle Lantern – Why would you need this when you have a headlamp.
Instant Cold Packs – What in the heck are these?
Bandanas – Most people are fine with one
TNF Shirt – Why this extra shirt? If you want something for sleeping in, you can get something lighter
REI Sahara Down Bag – Obviously you could go a lot lighter here, but of course that costs money.
BA Seedhouse SL2 – I owned and used a SL1 for years so I like the tents, but it is a bit much for solo use.
