The name of this glacier is a reference to a spectacular [icefall](/source/Icefall) at the head of Tennaya valley.[1] ## Geology At the head of Tennaya Glacier are rocks assigned to the upper assemblage of the [Ice Peak Formation](/source/Ice_Peak_Formation). They consist of [trachyte](/source/Trachyte), [benmoreite](/source/Benmoreite), [mugearite](/source/Mugearite), [tristanite](/source/Tristanite), [trachybasalt](/source/Trachybasalt) and [alkali basalt](/source/Alkali_basalt) that are in the form of lava flows, [lava domes](/source/Lava_dome) and [pyroclastic](/source/Pyroclastic_rock) [breccia](/source/Breccia). Also at the head of Tennaya Glacier is trachyte and [comenditic](/source/Comenditic) trachyte of the [Edziza Formation](/source/Edziza_Formation) which are in the form of pyroclastic breccia and [lahar](/source/Lahar) and [ash flow](/source/Ash_flow) deposits, as well as lava flows and endogenous [lava domes](/source/Lava_dome).[2] Just below the [trim line](/source/Trim_line) of Tennaya Glacier is a rounded hill completely covered with surficial deposits that may be the source of an alkali basalt flow of the [Big Raven Formation](/source/Big_Raven_Formation).[2][4] This lava flow travelled down Tennaya valley to near [Kakiddi Lake](/source/Kakiddi_Lake) via a narrow, wedge-shaped notch that formed as a result of erosion along the northern edge of an older and thicker [Kakiddi Formation](/source/Kakiddi_Formation) trachyte flow.[4] ## See also - [List of glaciers in Canada](/source/List_of_glaciers_in_Canada) - [Idiji Glacier](/source/Idiji_Glacier) - [Tencho Glacier](/source/Tencho_Glacier) - [Tenchen Glacier](/source/Tenchen_Glacier) ## References 1. ^ [***a***](#cite_ref-Tennaya_1-0) [***b***](#cite_ref-Tennaya_1-1) [***c***](#cite_ref-Tennaya_1-2) ["Tennaya Glacier"](https://apps.gov.bc.ca/pub/bcgnws/names/15031.html). *[BC Geographical Names](/source/BC_Geographical_Names)*.
