Question	—	What are the differences between prismatic, lensatic, mirrored, and optical sighting compasses? Background I am looking at compasses for backpacking and camping, and have come across more compass varieties than I had ever thought possible. Three terms that often come up together are "prismatic", "lensatic", "mirrored", and "optical". I do understand these types of compasses are for sighting, ... (more)	—	over 4 years ago
Answer	—	A: How to tell the difference between bobcats and house cats? The domestic cat and the bobcat look completely different, so it would be fairly easy to distinguish them. The bobbed tail cannot be relied on by itself, as there is a domestic breed of cat called the Manx that has a naturally bobbed tail, as well. However, this breed is a bit rare compared to all of...

Answer	—	A: How to fish from a kayak? Expanding on my comment Fishing from a kayak is not really that much different from fishing from any other watercraft. You have less space to work with, like fishing from a Personal Water Craft, but it's certainly doable. If you plan to do a serious amount of fishing from your kayak, or plan to be ...

Answer	—	A: How to create campfire which will burn overnight? Swedish Fire Log Yet another option is what is known as a Swedish torch or Canadian candle (especially if you have a chain saw available). This type of fire is much more useful as a camp stove as opposed to a heat source. It burns slowly, releasing most of its heat upward (toward the object being co... (more)	—	almost 6 years ago
Answer	—	A: How to create campfire which will burn overnight? Finnish Gap Fire Another option, besides the great answers already posted, is a Finnish gap fire, or Rakovalkea gap fire: You'll need a hand axe to carve notches into the logs to make them stable (kind of like a partial log cabin wall). Here's the directions from the site: How To... Build a Finni... (more)	—	almost 6 years ago
Question	—	What is the proper way to ford a shallow body of water in a back country situation? I was reading about off-roading just now, in particular best practices for conservation and safety, and I ended up on the Wikipedia page for fording. But that page deals mostly with either natural fords or man-made crossings that are deliberately below water level. Suppose you are in a situation whe... (more)	—	about 6 years ago
Answer	—	A: Are there resources for identifying dinosaur tracks? There are resources, but be aware that it is rather difficult to get a definitive answer. Here is a digital book published by the Earth Sciences department of the University of Bristol with a section on identifying track makers: http://palaeo.gly.bris.ac.uk/Palaeofiles/Tracks/default.html Here's a ...

Question	—	How are canvas tents made to be fire retardant? While reading through this question about adding a stove jack to a canvas tent originally lacking one, I wondered about the feasibility of making an existing canvas tent fire retardant. Is it simply a matter of adding an additional material or chemical layer to the canvas, or is the process of making... (more)	—	about 6 years ago
Answer	—	A: What species of dinosaur made these 3 toed 6 inch long tracks? The shape of that track reminds me of an ornithopod. There can be some confusion as to how to identify specifically which ornithopod might have made that track (Manus track preservation bias as a key factor for assessing trackmaker identity and quadrupedalism in basal ornithopods, Castanera D, Vila B...

Question	—	What animals have paw prints similar to a mountain lion such that the absence or presence of claw marks are the most reliable distinguishing feature? I was reading this question about how to identify mountain lion tracks just now, and noticed the remark at the end of the accepted answer about the lack of claw marks. I am a cat owner, so the lack of claw marks makes sense. But that led me to wonder: what animals would have a track that is similar i... (more)	—	about 6 years ago
Question	—	What's the proper way to establish a triaxial connection with carabiners? I love free climbing but have never climbed with ropes. While reading through this question, I realized I would never have thought of these scenarios, but due to the answers on that post, the physics in question makes sense. But this left me with a question: How would one achieve a triaxial connect... (more)	—	about 6 years ago
Answer	—	A: Alligator free Mangrove or Cypress swamps in the US? Alligators won't bother you. They will chill out on the floor of the water feature in question and patiently wait for you to pass by. I've skied on the Mississippi River before, as well as in other riverine regions in the South, and have as such spent considerable time bobbing in the water, waiting f... (more)	—	about 6 years ago
Answer	—	A: What is this 40 cm long greenish and golden shining fish with brown fins? Adding to @acpilot's answer, it appears New Brunswick, while not part of the native range of the smallmouth bass, is part of the expanded range of the fish. That further leads to a possible confirmation of the species. Here is the native and expanded range of the species in the United States accordin... (more)	—	almost 7 years ago
Answer	—	A: Footwear for one month in wet climate In a word: sandals There's a reason everyone you'll be around also wears sandals. But you'll want the same thong sandals or "flip flops" that they wear, since you'll be taking them off all the time (entering stores, homes, etc. If you see a pile of shoes, add yours to the pile.)

Question	—	Is there an organization for adults to learn outdoor skills with their kids? I had to tie down a tree last night since recent storms broke the guy lines I had placed when I planted it, and I used a tautline knot how-to I found online to tie it, since I was never a Scout. After reading a comment by @KRyan on a recent question, and considering my recent face-to-face with my ine... (more)	—	almost 7 years ago
Question	—	Are longer kayaks faster than shorter ones? I've been researching which kayak I'd like to buy, and I keep coming across the notion that longer kayaks are faster than shorter ones. I can understand that shorter kayaks have a greater tendency to alter course with each stroke, thus affecting your overall forward velocity, but if you correct for t... (more)	—	almost 7 years ago
Question	—	What is a "stitch-and-glue" kayak? I decided to kill some time today and look at pictures of wooden kayaks online. I kept seeing the phrase "stitch-and-glue" with respect to some of the kayaks. What does this term mean? (more)	—	about 10 years ago
