I can only comment on what I've seen, and that covers over 50 years of observations on hunting in Western Montana.
Back during my tender years the kids got the hand me down rifles, whether it fit the kid or not. Most hunters wore poorly constructed boots that rarely were warm, or dry and never insulated. Usually it wasn't a matter how many tumbles you fell down the mountain but how many times a day you'd do lt. I had a 25 -35 model 94 Winchester that I carried my first year or two I think. Dad strung a rope over the barrel, and around the pistol grip for me. Of course it sucked. Most of our rifles had iron open sites of sorts, buck-horn, peep, etc. Shot my first Elk and deer with peep sight .300 Savage rifle. First nice buck with buck horn sight .308 at over 200 yrds. I remember the front sight on the rifle practically covered the deer up at that range. God smiled on me early. Got my first 4 x Weaver scope when I turned 15 years of age.
Many already pointed out that wool plaid jackets ruled the day and only when things got wet and cold did you break out the wool pants. Most of us used blue jeans over cotton long johns. During my tender years very few people could afford 4 wheel drive vehicles. Our family worked very hard to put together the funding to buy 2 Willey's Jeep Station wagons. Both had PTO winches on the front ends. There was no laws about off roading back then, so if we killed game anywhere there was an attempt to get as close as possible. I actually saw my uncle (4 years in the big war) dangle that green Willey's of his down a rock face to retrieve a bull another uncle killed. We all hunted together as a family unit, and the hunting was intended to get the winters meat supply. I saw horns tired in trees and left all the time back then. We never camped out, because living in Hamilton back then was a good base camp in it'self. You really didn't have to travel all that far. Six miles and you were hunting!
Much of the country was still virgin as far as roads and logging went. There was some roads punched in to log the big (30,000 acre Sleeping child fire of 1961) fires we had back then but that was about it. That was soon to change though, as there was a push to make roadless lands Wilderness, so there was a race to road and log as much as possible before it could be designated. The Bitterroot Forest was a very beautiful then. There was main arterial roads into most of the main drainage's, but far fewer collector roads than we have today. We used the road systems to get us up and above certain elk rich drainage's and then hunted down through them in a coordinated effort to jump game back and forth to each other. You could always find big bulls, and big buck deer. The landscape was far bigger and wilder than it is today for certain. We always felt that we had room to roam were no man had gone before. Well I can tell you that there is no stone that has not been unturned, nor any drainage that hasn't seen a man there in today's hunting environment. She all gets hit.
My first year hunting I thought 6 x 6 point bulls were the norm. We took 6 bulls of that size during my first legal year of hunting. You wore your knife, bullets, and a drag rope on your belt, or the rope was your belt with those things attached. I had a hat with pull down ear muffs, and some hunters wore stocking caps, so they could pull the cap down over their eyes for a cat nap while road hunting. You knew how to build fires and did it almost every day when snow flew.
Large predators were far and few in between, there was more coyotes, and bobcats though. Saw one Grizzly in 73 on top of Sleeping Child White Stallion area. We figured it was a bad bear the Park Service dumped. Saw a few cat tracks, but the bounty system on cats had just ended.
Very few hunters had optics on their rifles let alone for use as bino's for glassing. Much of the glassing was done with a scoped rifle.
There was lots of hunting camps in the hills back then, but mostly from NR hunters,and people from other parts of the state. The Bitterroot had one of the only either sex Elk seasons in the state back then and it drew a lot of hunters from all over. We had the Eastern invasion back in those days. Totally reverse of what's going on today. There was around 50,000 hunters back then, compared to over 140,000 today. Archery came in a few years later and very few people partook in it.
I never dreamed we would have elk living in the urban environments like we do today. Some elk migrated down during snow events, but after a few shots they learned their lessons quickly. Today it's not uncommon to see elk along side of hwy 93 at the leaving Hamilton sign. There might be as many Elk in the high country today as there was back then, but there wasn't many then.
With all the game I witnessed taken for years, there was no one getting "Stoked", or "High Fived". There wasn't hero shots taken, (like others have already stated).In fact a camera was considered bad luck to have and left at home. Nobody ever yelled out, screamed or cried when a animal was taken. It was considered good fortune and maybe a gift from god to get a elk. It was big news to all when a Elk was harvested. Everyone in town knew who got lucky. There was always a canteen of really hot whiskey that was passed around after the game was loaded. Even 12 year olds took the shot of whiskey. It was a right of passage back then.
Today's hunters have great gear, drive great vehicles that are very dependable and get you where ever you want to go. You have camping gear that will keep you warm and dry. Have equipment that can shoot thousands of yards, can tell you exactly how far that animal is to shoot, and can look over a mountain a mile away and maybe,(not really but close) see a turd on a gnats ass. It's far more comfortable, and civilized to go hunting today than yesteryear.
