This is the classic wide open gully to the left of the Pinnacle Buttress. After an initial easy section, you can choose a number of variations, all relatively moderate, which lead to much easier ground just below the Alpine Gardens. It is worth noting that due to the ample low-angle snow slope above the climb, Odell's is particularly vulnerable to avalanche danger. Be very careful in assessing conditions and pay attention to the USFS forecasts. tuckerman.org/safety/safety.ht... tuckerman.org/avalanche/index....
A number of serious accidents/episodes have occurred with regard to this moderate climb the most famous of which was the 1982 Hugh Herr/Jeff Batzer rescue. Odell's was the last ice climb I did in New Hampshire and thoughts of others' previous mishaps plagued what should have been a relatively mellow solo climb, especially when the wet heavy snow thumped and subsided as I kicked my way up the final stretch of the gully. Be careful up here.
Easily located just left of the Pinnacle Buttress. Descend by heading south across the Alpine Gardens towards Lion's Head or more quickly east down the Escape Hatch. Make sure that you have a good sense of direction and a compass if the weather deteriorates.
