Re: Large Predator Scat ID - North Fork Nehalem - Tillamook Forest

The tapered tip is indicative of cougar. Apparently cougar leave their scat as calling cards for other cougars. Out in the open where they are likely to be recognized as a part of a land claim. Or so I heard and observed during a class on tracking.

Re: DEET Disaster Cleanup?

DEET is an inconveniently good solvent. I think the original study that claimed insect repellent equivalence is at www.ncbi.nlm.nih.gov/pmc/articles/PMC4270489 . That study was done in SE Asia and tested picaridin at 20% against DEET at 20% -- only against mosquitos. More powerful formulations were ...

Re: driving bennet pass road/gunsight butte (gumjuwac area)

Backing up on the Terrible Traverse would be "exciting", even with a spotter walking backward behind providing directions. Narrow; a possibly fatal drop on one side; the need in Tercel to pick a line to save the undercarriage and oil sump. One skillful driver can travel forward on that section of ro...

Re: Hike conditioning: do lots of short hikes prepare you for long ones?

I should have said, "other things equal", which in a complex system such as the human body, is never the case. At question is the work done. Clearly holds for lifting a weight to a mountain top, or to fighting a head wind. The automobile experiment provided me with a datapoint fitting the power rule...

Re: Hike conditioning: do lots of short hikes prepare you for long ones?

Pure physics: kinetic energy varies as mass times velocity squared for a given distance. you get there faster with higher speed, so cubed. I've checked this with an engineer friend in a car with various speed head winds and car speeds. With running the gate changes making the flats a matter of compa...

Re: Hike conditioning: do lots of short hikes prepare you for long ones?

Do lots of short hikes prepare you for long ones? No. There is fitness, and there is pacing. Experience adjusts the way we use our energy over the long haul of a day or week, with a large pack or small, and as the grade changes or the footing. Muscles in use change, and the goal is to tire them all ...

Re: Need to Find a Benchmark in the Woods

This BM in Forest Park may offer the quarter mile hike:
LATITUDE 45 34 33.27494(N)
LONGITUDE 122 46 16.21671(W)

East Zigzag Mountain's would, but it's snow season.

Re: I tried a barometric altimeter, seems to work well

The subject is a bit more complex, since a digital device has to infer altitude and their changes by a sampling procedure, whereas you read an analog altimeter directly. My old analog Thommens repeated altitudes regularly. Caught topo map elevation changes well every time. In summer, when high press...

Re: Tent with Mesh or Solid Fabric?

In my experience, on a well-pitched tent the condensation is on the fly. As long as the fly is separated from the body of the tent, neither kind of interior is wet from condensation. The fly, becoming wet, may sag more than the body of the tent; so beware. The greatest source of condensation can be ...
