In 1959, the addition of Alaska and Hawaii as the 49th and 50th states, respectively, disrupted the numbering system and made it much less prominent. Councils generally resumed use of geographical names (e.g., the Flint River Council or the Four Lakes Council) and provided their council number only when giving annual data to the central organization. Use of numbers to identify councils fell into further disuse when some of the smaller local councils found that it was in their best interest to combine with neighboring councils; for example, the Cumberland Council in Somerset, Kentucky combined with the Bluegrass Council in Lexington, Kentucky, and three Councils in northwest Texas combined to become the Northwest Texas Council.
