Rather than give a blow-by-blow description of each route, eliminating the sense of adventure, I aim to provide just enough information to get you into serious troub... I mean, just enough information to help you 1) choose routes appropriate for your group, 2) find your way, and 3) bring the right gear for the descent.
Each canyon contains a set of info tabs: Profile, Approach, The Business, Exit, Maps & Info, Trip Reports, and Gallery. While not all descriptions contain sufficient detail to fill all these tabs, all canyons contain Profile information.

Canyon Profile
The Canyon Profile each canyon's essential information. Canyoneers can get a sense of a canyon's technical challenges, required equipment, and overall character from the Profile information.
LOGISTICS
Rating includes the technical rating, the water volume rating, and my subjective rating of the quality via a "Star System." Understanding the ratings is important to using this guide; please see Understanding Canyon Ratings if you are unfamiliar with the ACA Canyon Rating system.
Season states the normal time of year to visit the canyon, usually with an explanation as to why. You may descend in other seasons, of course, but the description is tailored for the recommended season.
Time Commitment gives the time usually taken by competent, fit adults travelling in small teams, moving at a good pace... but allowing for the usual poking around and picture-taking. Larger groups will usually take more time. People new to canyoneering and not yet proficient at technical canyons should allow 50% to 100% more time to descend the routes. The times stated are usually based on several descents with a variety of groups.
Longest Rappel is the length of the longest rap. Most parties will want to bring at least TWICE this length of rope.
Access briefly describes how to reach the canyon trailhead, as well as any necessary vehicle shuttles. More detailed information in the "Approach" tab.
Permit Required? indicates whether your group needs a permit from the agency managing the canyon resource.
Emergency tells you who to contact in the event of an emergency.
EQUIPMENT
Essentials describes special equipment required to complete the route safely, over and above the "standard kit" appropriate for to the technical and water ratings.We usually state "Helmet, Rappelling Gear, Webbing and Rings" just to remind you that these are essential on every trip. ALWAYS bring water, food, a pack, decent shoes and a map.

For technical canyons, add a helmet, a harness, a rappel device, slings, and enough webbing and rapid links to establish or re-sling anchors in the canyon. More advanced canyons may require pack/Pot Shot tossing, or hooking out of potholes. A bolt kit is not required for routes listed in this guide (with a few exceptions, as noted).
***Common Sense should be listed in every equipment list, but is implied, rather than explicitly stated. Bring it along.***
Bringing along the 'required gear' does not make you safe, but not bringing along the required gear might make you unsafe.
Cold Water Protection suggests whether your party will want insulation from cold water using wetsuits or drysuits, and under what conditions.
Drinking Water indicates availability of reliable drinking water. Found water requires filtering to be safely consumed. Most canyoneers carry sufficient water for the day from the start.
DIFFICULTIES
Flash Flood Risk offers a generalized assesement, based on canyon topography, drainage size, and escapability. Almost every canyon adventure here has some degree of flash flood danger. I give a rather general rating and a few points to think about. Flash flood awareness is an important skill to bring to the canyoneering environment.
Skills Required offers a brief description of the difficulties found on the adventure, as I found it. This includes rappels, climbing problems, swimming/wading problems, exposed climbs, difficult anchors and navigational difficulties. Conditions change from day to day, and season to season. You will find the water level of pools and the wetness of canyons has a strong affect on difficulty, and can vary greatly.
Anchors describes the type and/or quality of the anchors. These can change drastically due to human and/or natural intervention.
The sport of technical canyoneering is changing rapidly as it grows and develops. What will happen to our beautiful wild canyons of the Colorado Plateau? Our impact on the wilderness canyons has become significant. There is a danger our canyons will soon be littered with human artifacts, and the sport of canyoneering reduced to a "Clip and Go" experience. Bolts are considered appropriate in the high-usage canyons of Zion, but generally inappropriate elsewhere in Utah. Please do not add bolts to canyons - instead, learn how to descend canyons safely using natural anchors.
Through conversation, we can develop a consensus about what is, and what is not, appropriate for our canyons. My own contribution to the conversation is Ethics & Style. Please read this section and ponder how your actions impact the environment and the experience of other canyoneers.
The on-line discussion at the Canyons E-Group is a good place to socialize, be socialized and chat with others about all things canyons.
