horizon. here is where the bear and the antelope play. but the bison dominates. you're looking at what may be the last free ranging purebred herd of wild bison in north america. >> look at the valley full of by son. it is primitive america. probably as close as you can get to what this part of the country looked like in the early 1700s. and 1800s. and it's really it's a treasure. dan is the superintendent at yellowstone national park. bison roam its 2.2 million acres. an area nearly as big as rhode island and delaware combined. but little about scale impresses america's largest land animal. a mature bison bull stand 6 feet tall and can weigh more than a ton. >> formidable. not many fullbacks would look to approach the line. so imposing andet

disappear. >> how dire did it get? >> well in yellowstone national park there were less than 25 animals. it is one of the greatest wildlife conservation stories in the history of the united states. here's why this conversation comeback is so remarkable. in the 1800s, as many as 60 million bison were hunted nearly into extinction. 60 million. they were targets. in the ugly side of how the west was won. the american bison, the symbol of the great plains, once roamed from nevada to mississippi. in the 100s, pioneers pushed west. bison were in the way. tens of millions were killed by cattle ranchers, homesteaders and u.s. troops. sport hunters shot by son from moving trains. as the animals disappeared so did native american tribes who for centuries relied on bison for food, clothing shelter and tools.

we call them buffalo. >> because? >> we think of by son as a white man term. >> irving carlson belong to blackfeet tribe. he is also president of the intertribal buffalo council, representing 60 tribe whose believe by son also have great spiritual significance. >> buffalo, are everything to tribes. we survived on them that if took care of us. >> reporter: what was the great buffalo slaughter really all about to you? >> if you got rid of the buffalo then consequently get rid of the indian. >> reporter: by 18 # 3, nearly all bison were gone. congress even sent soldiers to yellowstone to protect the final survivors from poachers. conservationists including president teddy roosevelt intervene to protect and restore the population. roughly 5,000 by son live at yellowstone today. this come back story. how improbable was it?

effort to restore what could have been an endangered species. >> rick wallen the chief by son biologist oversees a unique herd. >> you can't see this kind of abundance anywhere else. >> reporter: most of america's roughly half million by son today are managed as domestic live stock. many have cross bred with cattle. not yellowstone's herd. >> yellowstone bison probably represent one of the populations that truly have all of the ecological, evolutionary drivers that shape the species. this is as good as it gets. >> reporter: also the herd's calving season which brings us to yellowstone's by son challenge and controversy. managing the herd's growth. when the by son migrate outside the park, neighboring ranchers have killed them. they say they're worried the animals will spread brisolosis, a disease harmful to pregnant cattle. inside the park h

limits. under a federal state agreement, every year the herd has to be reduced by 10%. several hundred get sent for processing to tribes. which distribute the hide and meat. >> when you see these guys make you feel good? >> it does. >> but the current approach seems to satisfy no one including irving carlson who also belongs to the by son management coalition. he says these animals should roam free inside and outside of the park? or be returned to what he calls indian country. >> they're wild life. they belong on the land. they belong to the land. they're part of the land t. >> they're also part of yellowstone's future. >> i think there is madele ground. we can get more by son on the landscape. we can diminish, to eliminate the fear of this spread of the disease. we can honor the cultural significance of by son for the native am cerican community. >> thing of it as aay

>> reporter: there was only one marine there with a strap like that. so here is harold schultz. there is that loose liner strap. schultz survived the war, but for the rest of his life never said publicly he was in the picture. >> harold schultz never made any claims which is incredible in today's world. >> reporter: don't think less of bradley. who was wounded, received the navy cross, and has since passed away. >> nothing can change kind of the sacrifice and what those marines on iwo jima went through and huh they served their country. saved our nation. no matter the names, the image remains as powerful as the moment it was taken seven decades ago. david martin, quantico, virginia. that's the "cbs overnight news" for this tuesday. for some of you the news continues. for others, check back with us a little later for the morning news. and cbs this morning. from the broadcast center in new york city.
