River Gipping
During 1791, when the Trustees were negotiating with John Rennie, they had asked him to assess an extension of the navigation from Stowmarket to the River Lark at Bury St Edmunds, but this was not pursued. With the navigation thriving, there were two proposals for canals from Ipswich to Eye, Suffolk in 1819. A meeting was held in January at Eye, which was chaired by Charles Cornwallis, 2nd Marquess Cornwallis. It considered two reports, one proposed by the civil engineer William Cubitt, which involved a tunnel through the hills at Mendlesham, with the estimated cost exceeding £100,000, and another, for a canal over the hills, costing £80,000. Both were thought to be too expensive to implement, but a third proposal emerged, for an extension from the River Gipping at Needham Market, which would follow the valley of a tributary through Creeting St Mary to Earl Stonham, where a basin would be built beside the turnpike road (now the A140 road). This would enable waggons to make a round trip from Eye in a single day, rather than the two days that a trip to Ipswich took. The scheme was estimated to cost £12,000, and shares in it were offered at the meeting. Although many were taken up, the scheme did not advance any further.
Gibbon River
The Gibbon River rises in the center of the park at Grebe Lake. It flows for a short distance into Wolf Lake. Below Wolf Lake, the river flows through Virginia Cascades into the Norris valley. It flows near the Norris Geyser Basin and through the Gibbon Geyser Basin. From there it flows through the Gibbon River Canyon to its confluence with the Firehole River to form the Madison River. Early maps listed the river as Gibbons Fork or the East Fork of the Madison River. The river between Norris and Madison Junction is paralleled by the Grand Loop Road. The river, along with Gibbon Falls, is named for Colonel John Gibbon, U.S. Army who participated in the 1872 Hayden Geological Survey of Yellowstone.
