Final answer:
The question asks for the date of the first Miss Ponoka Stampede, a historical rodeo event in Ponoka, Alberta. However, the information provided in the reference is about the National Council of Women in 1898 and is not related to the Ponoka Stampede, making it impossible to provide the requested date.
Step-by-step explanation:
The question 'When was the first Miss Ponoka Stampede?' pertains to a historical event. The Ponoka Stampede is an annual rodeo event in Ponoka, Alberta, Canada. However, the details provided in the reference do not directly correspond to the Ponoka Stampede or the Miss Ponoka Stampede which means that the date of the first Miss Ponoka Stampede cannot be ascertained from the information given. The reference provided mentions the National Council of Women at Rideau Hall Aberdeen in 1898, but this event is not related to the Ponoka Stampede. Without the correct historical information or sources specifically detailing the history of the Miss Ponoka Stampede, providing an accurate date for the first event is not possible.
