Two options for naming:
Roadie option – describe the section – ‘slight up’, ‘tree covered hill’, ‘steep up’ – in fairly generic terms. DO NOT consider using a geographically correct name such as White Hill, Gladstone Pass or similar.
MTB option – Describe the section, geographic terms are allowed this time, ‘descent to river’, ‘white hill climb’, ‘roller coaster ride’. DO NOT use the informal trail naming system that MTBs have been using since the repack era. Swollen uvula, F4 trail, repack etc. etc.
Hope that clarifies the conventions.
