Douze heures, tout compris, avec un guide qui aborde la géologie, l'écologie, le climat, l'histoire et les légendes de cette région, ainsi que l'histoire des terres publiques américaines. La marche est l'essentiel. Forêts, tubes de lave, et cascades là où la route le permet. Ape Cave est le plus long tube de lave continu d'Amérique du Nord. À l'intérieur, la température reste à 42 °F, 5,5 °C, quel que soit le temps dehors : prévois plusieurs couches et des chaussures adaptées pour crapahuter. Essuie ces chaussures avant d'entrer : des chauves-souris vivent ici et le syndrome du museau blanc se transmet par les chaussures. Le Trail of Two Forests traverse une forêt de moulages de lave, pleine de puits et de tunnels là où se dressaient autrefois des arbres. Si la météo le permet, la journée atteint le point de vue sur le cratère le plus proche accessible en véhicule, et le pique-nique du déjeuner s'y prend, au-dessus de Spirit Lake, face à la montagne. 357 marches mènent au panorama complet, et par temps clair il embrasse quatre stratovolcans à la fois : St Helens, Rainier, Adams et Hood. Le Johnston Ridge Observatory se dresse là où David Johnston lança par radio « Vancouver! Vancouver! This is it! » le matin du 18 mai 1980. Lava Canyon est une andésite gris-bleu polie par le lahar de 1980, survenu lorsque des coulées pyroclastiques firent fondre le glacier Shoestring, et traversée aujourd'hui par des cascades couleur saphir. Annule au moins 24 heures avant le départ pour un remboursement intégral.

  1. 523 NE 19th Ave, Portland

  2. Mount St. Helens

    The trip covers Mount St Helens and the country around it with a naturalist guide, who handles the geology, ecology, climate, history and legends of the area, and the history of US public lands. The walks go near waterfalls, through lava tubes and into old growth forest, with stops both inside and outside the National Volcanic Monument.

  3. Ape Cave Lava Tubes

    The longest continuous lava tube in North America. The cave holds 42F, 5.5C, however hot the day is outside, so bring layers. Wear shoes you can scramble in, and wipe them before going in: this is a bat roost, and white-nose syndrome travels on boots.

  4. Trail of Two Forests Trail

    A lava mould forest, with wells and tunnels where trees once stood. Children take some persuading to leave.

  5. WIndy Ridge Viewpoint

    Weather permitting, the closest viewpoint into the crater that any vehicle can reach, and where the picnic lunch is eaten, over Spirit Lake with the mountain in front. 357 steps lead up to the full panorama. On a clear day it takes in four stratovolcanoes: St Helens, Rainier, Adams and Hood.

  6. Johnston Ridge Observatory

    The spot where David Johnston got on the radio and shouted "Vancouver! Vancouver! This is it!" on the morning of 18 May 1980.

  7. Mount St. Helens Visitor Center

    The visitor centre with the most detailed account of the mountain's history and geology.

  8. Lava Canyon

    Sapphire waterfalls running over blue-grey andesite, scoured smooth by the 1980 lahar that came when pyroclastic flows melted the Shoestring Glacier.

  9. Coldwater Ridge Visitor Center

    A deliberately retro visitor centre: a Mount St Helens film from around 1985, and a 1990s park ranger statue in the manner of Disneyland's Haunted Mansion, who delivers a lecture.

  10. 523 NE 19th Ave, Portland
