Archaeologists Tracked Lewis and Clark by Following Their Trail of Laxatives

How do you follow a trail more than 200 years quondam , when even the maps they used uncertain ? You look for specific historic deposits . And famed explorers of the Louisiana Purchase , Lewis and Clark , made some very strange ones .

A year after President Thomas Jefferson buy a lot of country from the French in 1803 , he sent out Meriwether Lewis and William Clark to get a look at what exactly he ’d bribe . The two commanded an expedition that set off out in St. Louis and made its room to the Pacific coast . Some part of their trail are well - live , while others remained lose to historians for yr . People knew approximately where Lewis and Clark made refugee camp , but they could n’t find the actual sites . And even if they happened to come across an old camp land site , it was difficult to tell which actual camper had made this fire , or shorten down that tree , or dug that latrine .

Eventually , research worker came across some data that helped clarify things … and that selective information total from their latrines . Lewis and Clark were fairly well - fit and well - aim , even if only by the criterion of the day . Given what those standard were , it ’s surprising that theyonly lost one personduring their trek . According to their own track record , they bled people who were febrile , they gave purgatives to people who mat fallible , and they administered K nitrate ( a preservative reserve for salt ) to people suffer from heat shot and dehydration . They also brought alongthe admiration drug of the day , mercury chloride ( otherwise acknowledge as calomel ) , as a anovulant , a tincture , and an ointment .

Calomel was often used to treat those with syphilis ( mercurydoes work against the bacterium that causes syphilis , but it takes out the server as well , so do n’t try it at home ) along with nigh everything else , including constipation . And an outing that deplete primarily the biz they could take hold of along the way would have stomach from constipation regularly . In their journal , Lewis and Clark on a regular basis make short letter of someone having to take one of Dr. Rush ’s Bilious Pills(because irregularity was thought to be triggered by an excess of bile)and spending the day purgation .

If you know that you and your man are going to spend a day boot out everything they ’ve eaten for a week , you make certain to dig a latrine . Most of the atomic number 80 that the human beings take in went out of the arrangement again , which means that over a C by and by , historiographer and archaeologists were able-bodied to immobilise down where Lewis and Clark had stayed by testing onetime latrine contents for mercury .

Several sites have been learn exactly this elbow room . The most famous isTraveler ’s Rest , in Montana . So if any Montanans are reading this , and have a weekend free , go out to your land park and , as you look around , savour the fact that you ’ve been bless with clever researchers and famous latrines . But maybe do n’t pledge the water near a Lewis and Clark encampment .
