I’d be interested in someone with a Data Book going through and figuring out just what percentage of the trail has water carries of 20 miles or more in a dry year, and how many days on the trail in a hot year were over 100 degrees. I don’t disagree that there is some hot weather, some long carries, a few highway underpasses, etc, as you can see from my post.
But i do start shaking my head when descriptions read that this is the NORM on the PCT. Truly, in any year with any conditions on the PCT, your typical day will be like this:
High in the upper 70s, low in the 40s. 4 or 5 water sources along the way. 1-2 days out from town, 1-2 days to get to town. Lots of trees. 1 road crossing. 3-4 semi-abandoned jeep track crossings. No vehicles or horses. Several thru-hikers. No other hikers. Quiet outdoors. Animals if you are hiking by dawn. No mountain lions. No dragons. No weather threats.
For years other than my own i’m basing this on reading trail journals faithfully. There are lots of the exceptional days, but they are few and far between. Even if EVERY day in SoCal in a given year is 105 with no water (which it isn’t), that’s still only 1/5 of the trail.
It’s more important that PCT prospectives give thought to mental fatigue, and repetitive stress to their feet and knees. These are the things that kill hikes and/or make them no fun.
Anyway, to answer the ORIGINAL question, yes drop boxes every 3-7 days is very practical. You may prefer to do more buying as you go, especially for southern and northern California, since it requires less planning. In the High Sierra, you’ll have one carry that will be more than 7 days. You’ll read about it. The other big differences in planning is that you don’t need to worry about being geared up for sustained rains until Oregon, and that you do need to have some good maps and perhaps an ice axe for the High Sierra. The AT veterans i hiked with pretty much did great on the PCT and adored it. A few found they could do much bigger miles, and a couple of those actually got hurt from doing too many big mile days. A few had to get used to occasionally looking at a map at junctions, since there are no blazes. A few times maybe even a compass…maybe. Other than that, no problem. Go hike it.
