Coretta Scott King - John Steptoe Award winner In this “taut, eloquent first novel” (Booklist, starred review), a young Black boy wrestles with conflicting notions of revolution and family loyalty as he becomes involved with the Black Panthers in 1968 Chicago. The Time: 1968 The Place: Chicago For thirteen-year-old Sam, it’s not easy being the son of known civil rights activist Roland Childs. Especially when his older (and best friend), Stick, begins to drift away from him for no apparent reason. And then it happens: Sam finds something that changes everything forever. Sam has always had faith in his father, but when he finds literature about the Black Panthers under Stick’s bed, he’s not sure who to believe: his father or his best friend. Suddenly, nothing feels certain anymore. Sam wants to believe that his father is right: You can effect change without using violence. But as time goes on, Sam grows weary of standing by and watching as his friends and family suffer at the hands of racism in their own community. Sam beings to explore the Panthers with Stick, but soon he’s involved in something far more serious—and more dangerous—than he could have ever predicted. Sam is faced with a difficult decision. Will he follow his father or his brother? His mind or his heart? The rock or the river?

Pecos River style pictographs are one of the most complex forms of rock art worldwide. The dramatic prehistoric pictographs on the limestone overhangs of the lower Pecos and Devils Rivers in West Texas have been the subject of preservation and study since the 1930s, and dedicated research continues to this day. The medium is large-scale, polychrome pictographs in open rock shelter settings, emphasizing the animistic/shamanistic religion practiced by the local aboriginal peoples. Creating large-scale rock murals required intelligence, skill, and knowledge. These enigmatic images, some dating to 4,500 years ago and possibly earlier, depict strange, vaguely human and animal shapes and various geometric forms. While full understanding of the meaning of these images is abstruse, archaeologists and other scholars have identified what they believe to be patterns and religious themes, mixed with what could be figures and objects from everyday life in the local hunter-gatherer culture as it existed in the region centuries before the arrival of colonizing Europeans. Although interpretation of these pictographs remains controversial, in Pecos River Style Rock Art: A Prehistoric Iconography, James Burr Harrison Macrae contributes to the beginnings of a syntactic “grammar” for these images that can be applied in diverse contexts without direct reference to any particular interpretation. “The strength of structural-iconographic analysis,” Macrae writes, “is that it relies on repetitive patterns rather than idiosyncratic information, such as trying to make broad inferences from one or only a few sites.” Pecos River Style Rock Art offers the framework of an empirical methodology for understanding these ancient artworks.

In the course of the hundreds of Rio Chama rafting trips that we've logged during the last 30 years, none of us has ever had a bad trip. Such is the magic of the Rio Chama. No matter the weather, the water level, the season, the crowded Big Eddy boat ramp on a blistering Sunday afternoon, or even the coffee forgotten at home, the Rio Chama remains "The People's River." Its stunning beauty, plus its exceptional camping, user-friendly whitewater, and mostly predictable flows, combine to create one of the Southwest's premiere, multi-day, river running experiences.The spectacular, towering canyon walls of the Wild & Scenic section through the remote Chama River Canyon Wilderness is New Mexico's own "Grand Canyon." The geology of the Rio Chama is so exceptional that this river is ideally suited for a river guide with a geological theme. And so, following the release of the Rio Grande geologic river guide in 2011, we turned our (part-time) attention to the Rio Chama. Although most Rio Chama recreation is focused on the El Vado to Big Eddy stretch, thedecision was easily made to include the entire boatable section, from the highlands in Colorado to the confluence with the Rio Grande, as each section of the river displays its own visual spectacles and assortment of adventures. Plus, the geology is magnificent and diverse along the entire length of the river.

Come to the riverbank with Adrian Smith and cast a line on the wild side. 'Beautifully written account' Dave Simpson, The Guardian 'Writes beautifully' The Sun Welcome to the world of Adrian Smith, playing his Jackson guitar onstage to millions - while behind the scenes he explores far-flung rivers, seas and lakes, waterways and weirs, in a fearless quest for fishing nirvana. Hooked on the angling adrenaline rush since first catching perch from East London canals on outings with his father, Adrian grew up to be in one of Rock's most iconic bands. On tour, his gear went with him. The fish got bigger. The adventures more extreme. In Monsters of River and Rock you'll hear about his first sturgeon: a whopping 100-pounder from the roaring rapids of Canada's Fraser River that nearly wiped him out mid-Maiden tour. Then there's the close shave with a shark off the Virgin Islands whilst wading waist-deep for bonefish. Not to mention an enviable list of specimen coarse fish from the UK.

This is a thoroughly modern book on the traditional open canoe. It covers all aspects of the open canoe, from design to wilderness travel. What really sets it apart is its focus on canoeing techniques. Ray Goodwin is the UK's best known and (many would go so far as to say) foremost canoe coach. By introducing some of the latest canoeing performance skills, based on what he has discovered through decades of coaching and guiding, he sets out to inspire a new generation of paddlers. Through clear language and the use of photographs acquired over many years of paddling around the world, he shares some real insights of the reality of canoeing; sometimes gritty, but always enthralling. New in the 2nd edition is a section on 'vision pattern', a method for creating a mental map of a rapid. There is an expanded and re-written chapter on canoeing with children. There are more techniques for improvised sailing and more on advanced lining and tracking. It describes new solo rescue techniques and has many new inspirational canoe expedition examples. Ray has paddled extensively in Europe and his British canoe trips include the circumnavigation of Wales and the Irish Sea Crossing. In North America he has canoed the Rio Grande in the South and done trips as far north as the Arctic Circle, as well as doing two kayak descents of the Grand Canyon of the Colorado. In addition to being a British Canoe Union Level 5 Coach in Canoe, Inland Kayak, he holds a Mountain Instructor's Certificate and has led ice climbs on Kilimanjaro, Mount Kenya and in the Atlas Mountains. He runs his own coaching and guiding business, working at all levels from novice to the top BCU leadership and coaching qualifications courses.
