Just be mindful of where you put your hands and feet,\u201d park superintendent Jessica Moore told Cowboy State Daily.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">Wildlife researcher Emily Martin worked with prairie rattlers in Sinks Canyon for a few seasons. The snake population there is robust, although there are no estimates of just how many there are, she told Cowboy State Daily.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u201cI caught over 100 snakes in a season, and it was very unusual if I re-sighted a particular snake,\u201d said Martin, a Ph.D. candidate in the Department of Biological Sciences at the University of Idaho.<\/p>\n<p>Great Habitat<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">Prairie rattlers are generally shy and try to avoid people, she said. Dogs running off-leash are more at risk of getting bitten\u00a0because they like to run up to snakes and sniff them.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">Moore said that during the four years of her tenure so far, there have\u00a0been no reports of a human being bitten by a rattlesnake.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">One dog was reported bitten last year, she said.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">Training courses are available to teach dogs to avoid hazards such as <a href=\"https:\/\/cowboystatedaily.com\/2024\/10\/10\/wyoming-dogs-death-in-beaver-trap-inspires-new-training-course\/\" rel=\"noopener noreferrer nofollow\" target=\"_blank\">rattlesnakes<\/a>\u00a0and traps.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">Sinks Canyon attracts so many prairie rattlesnakes because it\u2019s an ideal habitat, with plenty of nooks and crannies for them to get \u201cbelow the frostline\u201d when they go dormant during the winter, Martin said.<\/p>\n<p><img class=\"_1lnx4c90 _1lnx4c93 _1lnx4c96 _1lnx4c98\" decoding=\"async\" loading=\"lazy\" height=\"900\" width=\"1600\"   src=\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2026\/08\/snake-transmitter.jpg\" alt=\"VHF transmitters are surgically implanted in rattlesnakes to track their movements around Sinks Canyon State Park near Lander.\" style=\"font-size:0\"\/>VHF transmitters are surgically implanted in rattlesnakes to track their movements around Sinks Canyon State Park near Lander. (Emily Martin)Battling Vipers Caught On Video<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">Wyoming has two species of rattlesnakes, Martin said: Prairie rattlers and midget faded rattlesnakes.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">Prairie rattlesnakes are more widely distributed. The midget faded rattlers are concentrated around Flaming Gorge Reservoir and Green River, she said.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">Wyoming prairie rattlesnakes are on the smaller side because the relatively high altitude and cool weather limit their active hunting season.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">The typical size for adults in Sinks Canyon is 3 to 3.5 feet from nose to vent, Martin said.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">The vent is a single external opening on the underside of a snake\u2019s body near the tail and is the exit point for waste and reproductive fluids.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u201cMost of these guys (in Sinks Canyon) are medium- to small-sized, although I\u2019m sure most people wouldn\u2019t think that walking up to one on the trail,\u201d Martin said.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">That\u2019s a relatively rare occurrence, she added.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">For the most part, snakes don\u2019t like hanging out around people, she said. And they\u2019re good at sensing people stomping toward them on the trails, giving them time to slither away.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">Though relatively rare, rattler sightings at Sinks Canyon can be spectacular.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">In August 2024, hiker Susannah Bletner was in just the right place at the right time to capture a video of two big male <a href=\"https:\/\/cowboystatedaily.com\/2024\/08\/05\/dancing-wyoming-rattlers-actually-rare-video-of-males-fighting-for-territory\/\" rel=\"noopener noreferrer nofollow\" target=\"_blank\">prairie rattlers battling<\/a>\u00a0to see which could lay claim to the territory and any female rattlesnakes in it.\u00a0<\/p>\n<p><img class=\"_1lnx4c90 _1lnx4c93 _1lnx4c96 _1lnx4c98\" decoding=\"async\" loading=\"lazy\" height=\"900\" width=\"1600\"   src=\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2026\/08\/Snake-Catch.jpg\" alt=\"Prairie rattlesnakes are thriving in Sinks Canyon State Park near Lander in part because of an abundance of food sources.\" style=\"font-size:0\"\/>Prairie rattlesnakes are thriving in Sinks Canyon State Park near Lander in part because of an abundance of food sources. (Emily Martin)\u2018Hey, Don\u2019t Step On Me\u2019\u00a0<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u201cRattlesnakes are really good at going undetected, which can be a double-edged sword,\u201d Martin said.\u00a0<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">On one hand, it keeps trouble from starting if people don\u2019t even know snakes are there most of the time, she said.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">On the other hand, the snakes are so well-camouflaged, Martin said that even she has \u201cwalked to within a foot or two of a snake\u201d without realizing it.\u00a0<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">Snakes would rather not bite people if they can help it, she said.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">If they\u2019re alarmed, rattlesnakes will \u201crear up and rattle,\u201d she said.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u201cIt\u2019s a \u2018Hey, don\u2019t step on me\u2019 sort of thing,\u201d Martin said.<\/p>\n<p>\u2018You\u2019re Really, Really Unlikely To Die\u2019<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">When snakes bite humans, it\u2019s usually because the person got extremely close with a hand or foot. Or, foolishly, tried picking up a snake, she said.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0Martin has never been bitten herself, but victims describe the initial pain as excruciating.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0\u201cIt sucks, but if you can get past that initial shock, that initial pain, typically, you can walk out\u201d and get help, she said.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0It\u2019s best to get to a hospital with antivenom within about two hours, Martin said.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0Any longer, and the victim might risk permanent tissue loss or nerve damage.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0\u201cYou\u2019re really, really unlikely to die\u201d from a rattlesnake bite, she said.<\/p>\n<p><img class=\"_1lnx4c90 _1lnx4c93 _1lnx4c96 _1lnx4c98\" decoding=\"async\" loading=\"lazy\" height=\"900\" width=\"1600\"   src=\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2026\/08\/snake-tube.jpg\" alt=\"Prairie rattlesnakes are placed in tubes and knocked out with a gas, allowing tracking transmitters to be implanted.\" style=\"font-size:0\"\/>Prairie rattlesnakes are placed in tubes and knocked out with a gas, allowing tracking transmitters to be implanted. (Emily Martin)\u00a0\u2018Popped Like A Balloon\u2019<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0The prairie rattlers in Sinks Canyon are \u201crodent specialists\u201d and have a prey base consisting mostly of mice, pack rats, and cottontail rabbits, Martin said.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0\u201cThat\u2019s what their venom is for. They\u2019ll bite a prey animal and just trail it until it dies,\u201d she said.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0Then they\u2019ll swallow their prey whole.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0Contrary to popular belief, snakes can\u2019t completely unhinge their jaws, Martin said.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0Instead, their jaw joints are more \u201cfree-moving\u201d than other species, allowing them to open their mouths incredibly wide, she said.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0And an adult prairie rattlesnake can swallow a full-sized cottontail rabbit, she added.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0She recalled one instance, where a baby rattlesnake tried swallowing a mouse that was just too big for it.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0\u201cPoor guy just popped like a balloon,\u201d she said.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0Moore said that while prairie rattlesnakes knock down the rodent population in Sinks Canyon, they can in turn be eaten by raptors such as hawks and eagles.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0\u201cThey\u2019re really at both ends of the food chain, or the food web here,\u201d she said.<\/p>\n<p>\u00a0Snake Transmitters<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0Unlike deer, elk, wolves, bears, and other such critters, snakes can\u2019t be outfitted with tracking collars.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0So tracking transmitters have to be implanted in their bodies.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0Martin accomplishes that by catching snakes and putting them in tubes, where they\u2019re knocked out with gas.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0The transmitter, which is \u201cabout the size of a Mike and Ike candy,\u201d is inserted into the body cavity through an incision.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0\u201cI tuck it in underneath the ribcage, with the antenna running under the skin, pointed toward the head,\u201d Martin said.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0The incision is \u00a0sewn back up, and the snake is given a dose of painkiller to help with its recovery.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0Tracking data indicates that snakes\u2019 movements vary.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0One female \u201cspent her entire active season under a rock about the size of a mattress,\u201d Martin said.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u00a0On the other hand, she\u2019s tracked male rattlers roaming a territory of about two square miles.\u00a0<\/p>\n<p>Long Lives<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">Rattlesnakes can live up to 60 years or longer in the wild, Martin said.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">They\u2019re usually active until sometime in October, when they crawl into their dens and go into a dormant state called brumation, which is similar to hibernation in mammals.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">They might start emerging as early as March and are usually fully active by April.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">With their slow metabolisms, snakes can go a long time without feeding.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">\u201cA female rattlesnake can go a year without eating and still reproduce,\u201d she said.<\/p>\n<p>Translocation Might Not Work<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">Martin hopes her research will contribute to people being able to coexist with snakes.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">Moore said when snakes are reported in the park, it\u2019s usually because a snake came somewhere such as the parking lot to bask in the heat.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">Park personnel don\u2019t kill rattlesnakes, but instead catch them, put them safely in buckets and move them, she said.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">Moving snakes is a tricky business, Martin said. If they\u2019re not moved far enough, they might just go right back to the spot where people were freaking out.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">If they\u2019re moved too far, into unfamiliar territory, they might not survive, she said.<\/p>\n<p class=\"_1uhbe1z1 _1uhbe1z0\">Mark Heinz can be reached at <a href=\"https:\/\/cowboystatedaily.com\/2026\/08\/30\/sinks-canyon-is-full-of-prairie-rattlesnakes-and-yet-youre-unlikely-to-see-one\/mailto:mark@cowboystatedaily.com\" rel=\"noopener noreferrer nofollow\" target=\"_blank\">mark@cowboystatedaily.com<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"Though many visitors might not realize it, Sinks Canyon State Park near Lander is prairie rattlesnake central. \u201cWe&hellip;\n","protected":false},"author":2,"featured_media":831284,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[51],"tags":[79,201],"class_list":["post-831283","post","type-post","status-publish","format-standard","has-post-thumbnail","category-wildlife","tag-science","tag-wildlife"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/831283","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/comments?post=831283"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/831283\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media\/831284"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media?parent=831283"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/categories?post=831283"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/tags?post=831283"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
