Tye Chapman knows a thing or two about Mount Rainierāheās the operations manager for OR partner International Mountain Guides, after all. So we knew heād have all the dirty details when we asked him to write about the things most people donāt know about Rainier. Hereās what he said. The first recorded summit was in 1870 by General Hazard Stevens and Philemon Van Trump. Nowadays nearly 10,000 people attempt to climb Mt. Rainier every year. Ā There are more than 50 climbing routes on Mt. Rainier, with the vast majority of the climbers heading up via the Disappointment Cleaver Route. The second most popular route is the Emmons Glacier Route. Ā IMG partner George Dunn has the most summits of Mt. Rainier at 509 (and counting!). Ā Mount Rainier is an active stratovolcano. You can seeāand smellāevidence of this several places on the mountain, particularly on the summit, which has steam caves around the summit crater. Ā Youāve gotta poop in a bag when youāre on the mountain. Itās called the blue bag and itās exactly what you think it is. Itās a blue bag you poop in. The trickābesides pooping in itāis to make sure it gets back to Camp Muir or the trailhead in one piece. Ā Cell service on the mountain is spotty at best. There are a few secret spots we know about that are reliable to get a text or two out, but weāre not telling. Hint: One of them is located on a specific corner of the table at Camp Muirāif youāve been to Muir, you know the table weāre talking about. Verizon is better at Muir, and AT&T is better at the Flats or on the Emmons. Leave the T-Mobile phone at home. Ā Uphill traffic has the right-of-way. Theyāre doing the hard work, so let them pass. Ā On the Muir snowfield, stay in the boot pack on the way uphill. But more importantly, stay out of it on the way down. The uphill traffic has to work a lot harder if the boot pack is all blown out by the downhill traffic. Ā Slow and steady wins the race. What might feel slow to start probably feels just right later in the day. Ā Most climbers eat real food. Youāll never see a guide eating a Powerbar or a GU packet. Youāll see them eating sandwiches, fruit, bagels, chips, pizza, quesadillas, etc. If you donāt love it at sea level, youāre going to hate it on the upper mountain. 150-200 calories every hour or two between breakfast and dinner keeps the fire burning. Ā If you drink coffee at home, drink coffee on the mountain. Your bodyās addiction to the good stuff trumps the small negative effects that coffee might have. Ā It is worth it.
